Original commit message:
Add V8_DISABLE_PRESERVE_MOST for embedders to opt out of preserve_most
preserve_most changes the calling convention, which clang
encodes in the mangled name (e.g. "U" instead of "A" for cdecl in the
Microsoft C++ ABI). A consumer whose toolchain does not support
the attribute would reference a differently mangled symbol.
This patch adds a V8_DISABLE_PRESERVE_MOST to disable it, so that
it's possible to link to V8 using different toolchains, as long
as the value of it is set consistently.
