37d11fb0f0 Improvements in lithium code generation. Recognizing if some operands are constants, we can often save on registers and instructions.

f51b76425a MIPS: Generator objects can suspend
Port r14353 (f4bb81d1)

Original commit message:
* src/ast.h:
* src/parser.cc: Differentiate between the different kinds of yields, in
  anticipation of boxing return values.  Parse `return' into `yield' in
  a generator.

* src/runtime.h:
* src/runtime.cc (Runtime_SuspendJSGeneratorObject): New horrible
  runtime function: saves continuation, context, and operands into the
  generator object.

* src/arm/full-codegen-arm.cc (VisitYield):
* src/ia32/full-codegen-ia32.cc (VisitYield):
* src/x64/full-codegen-x64.cc (VisitYield): Arrange to call
  SuspendJSGeneratorObject.  If the call returns the hole, we suspend.
  Otherwise we resume.

BUG=v8:2355
TEST=These codepaths are tested when the generator is first invoked, and so
are covered by mjsunit/harmony/generators-objects.js.

a8521a9e77 RecordWriteStubs on ARM need to save FP registers
A previous change erroneously stopped saving fp registers for write stubs in
snapshotted code. This CL restores correct behavior, and makes sure code that
saves fp registers checks at runtime for 16 or 32 fp registers. Also fix a bug
in the arm simulator debugger.

8bbf942d75 Remove heap snapshot size limit.
As long as frontend now stores snapshots in external arrays
it doesn't make sense to check the collected snapshot size on the
backend side. In other words if backend has managed to fit the
collected snapshot into its memory, it should also fit into the
frontend's memory.
