thakis 5459468dd6 32-bit linux: Force 16-byte stack alignment. 
clang assumes 16-byte stack alignment, but incoming stack alignment isn't
always guaranteed to be that way.  It looks like v8 was lucky to not hit
this so far.

See https://crbug.com/418554 -- this makes v8's standalone config match
Chromium.  See also https://llvm.org/bugs/show_bug.cgi?id=21414

Maybe it's possible to change the caller of OnEntryHook() to guarantee
the right alignment, but matching Chromium's build flags here seems like
a good idea in general.
