search the existing key space.
- Pass a thread parameter where useful to library methods.

1. Add fast path smi multiply
2. Recognize more operands as likely smi: If they are the result
another CheckedSmiOp, or the result of a phi that has a known smi.
3. Fix guessing receiver cids of getters/setters based.
4. Try to specialize calls based on propagated receiver type first before
using guessed cids (which generates a call with checks + megamorphic slow path)

This removes the additional indirection to the VM's implementation
for all the factory constructors.
Additionally, it removes one class per typed data list type, thus reducing
snapshot and generated code size.

not on the signature type hash anymore. This makes fingerprints insensitive to
implementation details of the type system. The signature type hash was included
because, in the early days, the token stream of a function started at the
opening brace and did not include tokens representing the signature.

Super initializer calls get implicitly moved to the end of the initializer list, so we don't need the two-phase constructor protocol anymore.
Ryan, can you please look at the mirror changes and check wether I've missed something?

Minimize the number of dependencies of compiler-related files.
This is needed to remove whole .cc/.h files from a compiler-less VM binary which
can be used for running precompiled code.
* removed dependencies of object.cc on flow_graph_compiler.h and flow_graph_builder.h
* removed unnecessary includes from object.h

They just redirect to the native typed data list constructor. Inlining
them makes type propagation more precise. There is no size cost with always
inlining these since they just contain a constructor call.
Also, remove dead code from the inliner: Unoptimized code is not accessed during
optimized compilation anymore.

Make the compact linked hash map, which is the default implementation for Map
(including map literals), a VM-internal class.
This makes it easy to have more efficient serialization of maps (although for
now, the implementation is straight-forward).
Refactor the compact hash class hierarchy to enable the VM-internal class and
the rest (also the Set classes) to share a maximal amount of code, by using
two different bases for implicit/explicit fields.
Remove existing proof-of-concept, C++-based internal VM-class.

- Do some minor modifications to the intrinsifier code to not do redundant fingerprint checks and avoid code duplication.
These changes result in a text segment size savings of about 110k.

When reading from a byte array as floats or doubles, perform the
endianness correction before converting to a float or double
rather than the other way around. This is to avoid floating
point canonicalization changing the bytes before we put them
in the right order.
Unrelatedly, this change also adds armv5te as an architecture
needing extra time for tests to correct an oversight in my
last CL.

- don't manually truncate values before passing them to TypedData._[set|get]<Type> - these methods already have truncating semantics;
- don't call into runtime for endianess conversion, implement it in pure Dart instead (with an intent to provide optimized version on platforms that support fast byte-swapping instructions);
- force inlining of these methods (change the order of checks in the ShouldWeInline to guarantee inlining of whitelisted methods).
Unrelated change:
- tweak output of Function::CheckSourceFingerprint to be immediately copy&paste useful.

Moving the throw of RangeError out of the _throwRangeError helper
may benefit LICM, since that block is now considered a method exit (and
not part of a enclosing loop).
_throwRangeError was not inlined because the call site was considered
cold by invocation counters (most programs don't throw RangeError).
Also, I renamed some misleading names in the optimizer.
