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.

A DCHECK is guarding something which has previously been a memory

Use FastAsciiConvert (as used by Unibrow) for i18n-aware
case conversion with --icu_case_mapping.

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

This CL implements GetPossibleBreakpoints for wasm, by iterating over
all functions in the requested range and returning the location of all
instructions within that range.

The connection to the inspector will be added later, when setting
breakpoint also works for wasm: http://crrev.com/2536763002
