[Arm]: Optimize ConstantPoolBuilder::Populate code by minimizing calls to OffsetOfElementAt
...
Calling OffsetOfElementAt becomes expensive when compiling functions with many
constant pool entries. This was causing a regression in MandreelLatency due
to the time spent populating the constant pool array for large compiled
functions.
This change avoids calling OffsetOfElementAt for each entry, and instead keeps
track of the current offsets in ConstantPoolBuilder::Populate. This gives the
following improvements on a Nexus 5:
Inline CP | OOL CP (before CL) | OOL CP (after CL)
Mandreel: 4305 | 3961 | 4120
MandreelLatency: 2298 | 1198 | 1994
Octane Score: 5197 | 4982 | 5152

More OStreamsUse OStreams more often.
...
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

[Arm]: Enable use of extended out-of-line constant pool for Arm.
...
- Adds support to the Arm assembler to use extended constant pools.
- Update (set_)target_address_at to support extended constant pool load
updates.
- Replace Operand::is_single_instruction with Operand::instructions_required
Due to the fact that different constant pool load types require different
numbers of instructions.
- Various cleanups of ConstantPoolBuilder to cleaner integration of the
extended constant pool building.
- Update GetRelocatedValue such that offsets to both map_check and bool_load
are explicitly provided, rather than location of bool_load being inferred
based on map_check, since the code inbetween is no longer of a predictable
size.
- Update MacroAssembler::GetRelocatedValueLocation() to add support for
getting a value from an extended constant pool entry.
- Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
when checking for debug breaks at constant pool load points.
- Change ConstantPoolIterateBody to iterate over both heap and code pointer in
the small section before moving onto the extended section, to work around the
requirement of the serializer that pointers are iterated in-order.
- Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
pools are now in the old pointer space (rather than code).

One of the fast cases in JSObject::MigrateFastToFast() should not be taken if the number of fields did not change.

Revert "Remove special ExecutableAccessorInfo handling based on flag"
...
Temporarily reverting until we figure out how to handle the API cases that use accessors to lazily compute values.
dataAttributeGetterCustom in V8MessageEventCustom (at least) overwrites itself with the computed value using ForceSet. We can either force such clients to first use ForceDelete before caching, use some other caching mechanism; or provide an API for lazily computed properties.

Remove special ExecutableAccessorInfo handling based on flag
...
This additionally removes special "prototype" handling for O.o, since it's broken; and added test.
