Currently, to find out a Promise's status and result, one has to use the
debug context. This is for example done in Node.js. This new API is a
better replacement, also in the context of the debug context being
deprecated eventually.

We have the BytecodeIterator with next() and has_next() methods, and
pc_offset() and current() accessors.
This CL adds an interface to iterate over the opcodes or offsets in a
C++ foreach loop.

This moves the platform-specific distinction to one place, and allows
to just include assembler-inl.h instead of macro-assembler.h to get the
correct inline functions defined in assembler.h (e.g.
RelocInfo::set_target_address).

This simplifies the mark getter enough to generate a branch-free check
on many architectures (e.g. using cmov on x64 or csel on ARM).

As a drive-by, we can now make the mark access const.

Previously, the Intl.DateTimeFormat constructor and other related paths had
a bug where the options bag passed in would be modified in place. This patch
makes V8's Intl implementation follow the specification's logic to avoid
such a modification.

Move FastAsciiConvert to src/string-case.cc so that it can be used
by both runtime-{string,i18n}.
