Set host_arch to ia32 on machines with a 32bit userland but a 64bit kernel.

I don't know if there are any v8 bots with that configuration, but it seems
like a good idea to have v8 be consistent with chromium and nacl here, so that
this works fine if such a bot is ever set up.

This is similar to https://codereview.chromium.org/342493002/ , but with a
detect_v8_host_arch.py script that handles the additional machine types that
standalone.gypi used to handle.

ARM64: updated literal pool implementation.

Currently the literal pool implemetation is inherited from the arm 32-bit port
and it shares the same limitations: 4k of range and 1000 entries max. In arm64
the load literal has a 1MB range giving us more flexibility.

Immutable entries are now shared.
