Fix yield inside with
This patch makes it so that suspending generators always saves the
context. Previously we erroneously assumed that if the operand stack
was empty, that the context would be unchanged, but that is not the case
with "with".
Fixing this brought out an interesting bug in the variable allocator.
Yield inside with will reference a context-allocated temporary holding
the generator object. Before the fix, this object was looked up in the
with context instead of the function context, because with contexts were
not being simulated during full-codegen. Previously this was OK as all
variables would be given LOOKUP allocation instead of CONTEXT, but the
context-allocated temporary invalidated this assumption. The fix is to
simulate the context chain more accurately in full-codegen.

Generators can resume
The generator object methods "next", "send", and "throw" now
include some inline assembly to set up a resumed stack frame. In some
common cases, we can just jump back into the frame to resume it.
Otherwise the resume code calls out to a runtime to fill in the operand
stack, rewind the handlers, and possibly to throw an exception.

Currently, the gap resolver doesn't handle moves from a ConstantOperand to a
DoubleRegister, but these kind of moves appeared when HConstant::EmitAtUses
was changed to allow special double values (-0, NaN, hole). So we should
either enhance the gap resolver or make sure that such moves don't happen.

* All Lithium instructions have an associated Hydrogen instruction now,
simplifying things.
* Consistently print <Lithium instruction number,Hydrogen value id> prefixes.
* Do not print uninteresting Lithium instructions like empty gaps, jumps to the
next instruction, etc.
* Removed special handling of HChange-like instructions, it is totally unclear
why they had this special treatment. If we really want to print more
information about Lithium instructions, we should do it in a totally way,
anyway (e.g. by unifying things with the generation of hydrogen*.cfg files).

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.

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.

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.
