Conceptually f() becomes f.call() where the .call method performs the actual
closure call. The closure call itself is implemented without a stub.

The check if the object called is a closure becomes a class-id check
which can be hoisted out of loops.

hausner@google.com ed24226376 Support deferred library prefix syntax 
First step towards deferred library support:
- Parse the “deferred as” import clause.
- Implement p.loadLibrary() which returns a future that
  completes when the library is loaded.
- Treat type annotations of deferred types as malformed.
- Throw NoSuchMethodError when calling functions from
  unloaded libraries.
- Libraries are still read synchronously, but items in the
  library won’t be visible through the deferred prefix until
  the future returned by loadLibrary() completes.

fschneider@google.com 37b30ab2ac Alternative fix for .call invocation of closures. 
This also covers "closurization" of the .call method.
This relies on the fact that f.call === f if f is a closure.
This means that adding a simple getter to _FunctionImpl that
 returns this is enough. No need for a separate dispatch.

This CL reverts the previous fix for issue 12602 (modulo the
additional tests).

fschneider@google.com f75ef2e6ab Fix invocation of closures via .call in the VM. 
Calling closures via .call does now work in the VM - it was working in
dart2js already.  Calling .call on a closure is implemented to go through
a dispatcher method. These dispatcher methods are automatically created and
cached in the same way as NoSuchMethod- or field-invocation dispatchers.

This CL does not change the way regular closure invocation works in
the VM. It is therefore performance-neutral for normal closure calls.

hausner@google.com ac559f643a Introduce cache of resolved names in library 
A name that is not resolved in the local scope gets looked up
in the global scope of the library to which the code being compiled
belongs. The local name dictionary gets searched first, then the
dictionary of each imported library (and and their re-exported
libraries.) Each dictionary lookup includes the lookup of the
mangled getter and setter names, which means that we concatenate
the same name many times.

This change introduces a cache that stores the result of a previous
name lookup, including negative lookup results. The latter is important
to speed up the resolution of names that are not in the global name
space, e.g. class members like .length in lists.

Experiments running dart2js (with VM option --compile_all) show
that this reduces the number of name mangling calls by a factor of 10
and speeds up compiling dart2js by 15%.

The bit has_finally was only used to skip the checking of the stack height
at return statements: There was an unused value floating on top of the
expression stack in unoptimized code if the finally block preceded a normal
return statement. Normallyi, that does not cause harm. Optimized code is not
affected since it has a fixed stack size for expression evaluation.

This CL fixes the stack height for functions with try-finally by introducing
a temporary local where the return value is saved before an inlined

hausner@google.com baf16bac5e Make safe points in generated code invisible to the debugger 
- remove some PC descriptors that are part of implicit, synthesized
  code, e.g. generated null checks in == methods, implicit constructors,
  implicitly generated code in user constructors, etc.
- ignore single step callbacks on PC descriptors that are part of
  synthesized code.

hausner@google.com 812467f0f6 Fix several little buglets with stepping 
No need to halt on single step if there is a breakpoint on the
same location. While looking at the resulting test failures, I
discovered that the step_in_equals test was not at all testing
what it was meant to test. It happened to pass because of a
related bug in the parser. Decided to abandon that test and
instead check that we can break at == even if one of the operands
is null.

Added ability to match line numbers in the debugger tests.

zra@google.com fdeff1ba17 Replaces LongJump with LongJumpScope. 
LongJump required explicitly restoring the old
long jump base before function return. This was
sometimes forgotten, leading to crashes. This
change puts the base restoration into the
destructor so that it happens automatically on
return.
