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.

Do not eagerly update allow_osr_at_loop_nesting_level.

Having debug break points prevents OSR. That causes
allow_osr_at_loop_nesting_level and the actually patched state
to go out of sync.

ARM: Fix inline assembly (r21949) for Clang.

Add a 'c' predicate to the immediate syscall number. This tells the
compiler to omit the leading '#' that immediates usually have in ARM.
The GNU assembler tolerates "ldr r7, =#1234" but Clang does not.
