kmillikin@google.com 3e78b2ad4a Reapply "Initial implementation of on-stack replacement (OSR)."
This reapplies SVN r24024 with a bugfix.

After OSR compilation, restore the pre-OSR code (which might be already
optimized) rather than the unoptimized code (which might have its entry
patched).  When the optimized code entry is patched it is only safe to call
it as a static call, not as an instance call.

kmillikin@google.com 0b39927d30 Initial implementation of on-stack replacement (OSR).
Add profiling support to select OSR candidates and launch the compiler
for OSR, followed by entry to the function at the OSR entry point.

Implemented only on IA32 and X64.  The initial implementation can be
improved in various ways --- specifically: tuning of profiling
parameters and incorporation of feedback about the actual values seen
at OSR entry.

fschneider@google.com 07966b62da Fix two bugs in the Dart VM's super-noSuchMethod invocation.
1. The result value of an expression 
"super.someMissingSetter = val" was incorrect in case of a noSuchMethod call.

To fix this I refactored the BuildStaticNoSuchMethod function. It now no longer
creates AST nodes and visits them, because the last argument may be needed saved
as a result value.

2. The evaluation order of "super[e1] = e2" was wrong in case of a noSuchMethod call.

asiva@google.com e33c2d4254 Delay Class parsing until the class is actually used.
Prior to this change the initial heap sizes were as follows:
ia32:
Size of isolate snapshot = 1230921
New space (0k of 32768k) Old space (1446k of 1604k)

X64:
Size of isolate snapshot = 1223943
New space (0k of 32768k) Old space (2630k of 2692k)


After this change the initial heap sizes are as follows:
ia32:
Size of isolate snapshot = 686443
New space (0k of 32768k) Old space (677k of 836k)

X64:
Size of isolate snapshot = 684731
New space (0k of 32768k) Old space (1220k of 1412k)

turnidge@google.com 0ddd4c04e9 Dart_PropagateError, take 2.
This change hopefully takes care of the non-mac build issues.  The
checked mode failures are fixed in a separate cl.

turnidge@google.com 9da62c5fea Add Dart_PropagateError.
This function can be used in native functions to properly pass all
errors up the stack.

Set the long jump base in the Compiler instead of outside of the
compiler.  A bunch of errors that used to be propagated through the
sticky_error are now propagated through return values.  This includes
all of the DartEntry and DartLibraryCall functions.

In particular, we no longer use the long jump to cross dart frames.
Instead errors are propagated across dart frames using the same
mechanism that we use for unhandled exceptions.  I've added assertions
to make sure that we only use the long jump when it is "safe".
