fschneider@google.com fe726e1971 Use parallel move resolver for optimized try-catch.
This CL has no change in functionality and is purely clean up and
refactoring. Instead of manually generating the moves at throwing
instructions in try-catch, construct a parallel move and use the resolver
to emit the native code. This eliminates a lot of duplicated code
from all platforms.

It will also allow to re-use stack space that is currently allocated
separately for each individual try-catch in a function.

I added a few more unrelated minor changes in various parts of the VM
* Simpilify guard code generation
* Resolve refactoring TODO in deoptimization
* Improve names

fschneider@google.com 16098ce25a Fix invalid aliasing in type propagation of AssertAssignable.
We have to create a copy when computing the initial type for AssertAssignable
instead of using the CompileType of the input operand. Aliasing can cause
invalid elimination of checks after strengthening of asserts.

fschneider@google.com 6abd6e326e Add mutable double boxes for fields.
This allows the optimizing compiler to generate unboxed loads/stores
to fields containing double values. The double value is stored
in a reusable double object.

Unboxed loads/stores are generated for optimized code. Unoptimized code
allocates a new double on loads. To avoid performance regressions
for fields that are only written few times (e.g. only in the constructor)
I put a heuristic in place that
compares the usage count of setters and getters. Unboxed operations
are only generated if the setter is invoked a significant amount of
times (threshold is 10% of getter invocations).

The CL is so big because it changes the way LocationSummmary
is allocated: We now have a bit to generate different summaries
for optimized and unoptimized code.

srdjan@google.com 98a1355ef9 Restoring the remaining CL 104893003. For instance call representing numerical comparisons and binary operations (double and Smi supported for now) that were never visited before optimization occurs, we guess the cids if one of the argument cids is known, e.g. ‘a == 1’ we guess that a is also going to be 1 thus avoiding emitting an IC-call in optimized code and propagating the type accordingly.
Remove AssertAssignableInstr::RecomputeType as it may cause incorrect behavior: it changes the type of its value based on input, the graph below will then incorrectly remove CheckSmi.

v27 <- BinaryMintOp:14(..

v28 <- AssertAssignable(v27)

zra@google.com daf539e2f9 Fixes a couple problems with GC of unoptimized code.
1. Instead of making a pass before the Marking phase,
   this change does not visit code pointers in functions
   during marking. Then after marking, if the code has
   still not been marked, code pointers in functions
   are nulled out.
2. Since code pointers in functions may be nulled out,
   functions are no longer used as proxies for code in
   deoptimization info.

fschneider@google.com b15bd6fe04 Cleanup of branch code generation (no change in functionality).
This CL is the first step in refactoring the way branches and comparisons
are generated.

1. Move helper functions from flow_graph_compiler_xyz.cc to
intermediate_language_xyz.cc.

2. Remove IL class ControlInstruction. It was only implemented by BranchInstr.
All functions provided are moved to BranchInstr.

3. When generating branch code for comparisons, pass the successor labels explicitly
instead of getting them from the branch. This will allow us to provide different labels
when materialize a bool value of a comparison.

4. Move some common code for IfThenElseInstr from the platform-specific files
into intermediate_language.cc and simplify it.

The goal is to enable if-conversion of arbitrary comparisons. Right now,
the code for == is hard-coded in IfThenElseInstr (and duplicated, too). This
means that e.g. "a < b ? 0 : 1" cannot be optimized.

As a result, IfThenElseInstr can be used to materialize the boolean  value of
a comparison. This way the complication of having ComparisonInstr both as a
normal instruction and as wrapped inside a BranchInstr can be simplified.
Comparisons would no longer appear as plain instructions in the IL, but only
wrapped inside either a Branch or an IfThenElse(true, false).

This is based on a previous uncommitted CL by vegorov@

It is rebased and fixes a bug in the MIPS implementation: BranchOnCondition
requires the comparison result in fixed registers CMPRES1/CMPRES2.

Remove register alias TMP1 (=TMP) and CMPRES (=CMPRES1). It is confusing to
have them around and easy to forget that they are actually the same.

fschneider@google.com 9031c80c88 Change == into an instance call to allow polymorphic inlining of ==.
In unoptimized code equality is now just another instance call.

The optimizer replaces it with a specialized implementation based on static
 type information and type feedback.

Many of the manual optimizations of == in the optimizer are now just handled
 by the generic inliner, plus polymorphic inlining of == calls is now possible.
This also eliminates the need for a lot of duplicated code in the backend.

I adapted the inlining heuristics to compensate for the slightly larger
inital flow graph size.

fschneider@google.com acb389dbf9 Optimize conditional branches that have same true/false targets.
Branches that have the same true/false target, or where both
target blocks reach the same common join block via empty blocks
can be replaced by a goto to the common join block.

In code like this

var a = unknown();
var b = null;
if (a == null || b == null) {
  ...
}

it eliminates the test (a == null) if b is known to be null. Until now,
the compiler could only eliminate the test for b, if a was known.

mlippautz@google.com 4fa46b7148 Introduce newline tokens into the token stream.
CL only introduces the tokens into the compressed token stream. We do not
use the newline tokens (yet).

Overhead:
snapshot: 6.4% (860k/808k)
compressed token stream (gen_snapshot): 21% (314312/259907)

fschneider@google.com ac08babf45 Polymorphic inlining of [] operations.
This CL adds the necessary parts to enable polymorphic
inlining of recognized methods. For now it handles only
[]-calls. This helps code that deals with e.g. growable
and fixed-length lists.

The basic idea is to adapt the code in the flow graph
optimizer so that it can be used from the generic inliner.
Currently this adds a bit of boilerplate code which I intend
to reduce when adding more recognized methods to be handled.
