bd99223cad MIPS: Improve write barriers in optimized code. 
Port r21630 (a21ff10)

Original commit message:
Use a cheaper RecordWriteForMap() to update the
write barrier for maps. And skip the value check
in RecordWriteField() when we statically know that
the value is in new space (and therefore has "pointers
to here are interesting" flag set).

97c962c255 Add support for extended constant pool arrays. 
This CL adds support for ConstantPoolArrays which contain an extended section.
This will be used to enable larger constant pools than can be addressed by a
single ldr with immediate offset instruction (which has a limit of a 4KB range).
Extended constant pools will have a small section, which is addressable via a
single ldr instruction, and an extended section, which will require a multi-
instruction sequence to load from.

Currently, no code uses the extended ConstantPoolArray's - this change will
be made in a followup CL.

A number of changes are made to the ConstantPoolArray object in order to
support this:
  - Small section layout is now entirely defined by the small layout bitmaps.
  - The ConstantPoolArray no longer extends FixedArrayBase since the length
    field is not useful for extended layouts.
  - Enums are used to represent the type of an entry and the layout section.
  - An iterator can be used to iterate through all elements of a given type.
  - A number of tests were added for these features.

There were no explicit tests for FuncNameInferrer (though, some tests might
implicitly rely on it working properly in the common cases). Afaics, there were
no tests which would exercise inferring two byte function names or escaped
function names.

61509aaea5 Support external startup data in V8. 
If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

0c8cd46302 ARM64: Restructure the L1 deopt jump table. 
This restructures the L1 deopt jump table so that the base address of
the L2 table is only loaded once. This significantly reduces the size of
the generated code because only one big immediate needs to be loaded.

The total size of all L1 deopt tables generated during Octane is almost
halved in size, from about 1105kB to 584kB.
