Support vtable_verify (new compiler option).
I'm in the process of adding a new option to the gcc compiler in ChromeOS, that does vtable pointer verification before virtual method calls. The new compiler flag is "-fvtable-verify=std" or "-fvtable-verify=preinit". I'm modifying the Chrome ebuild flag in Chrome OS to allow "USE=vtable_verify" and which causes 'use_vtable_verify' to be defined and set to 1.
In this CL I have modified common.gypi to add the compiler flag '-fvtable-verify=std' if it sees use_vtable_verify set to 1; and I have modified allocator.gyp to change '-fvtable-verify=std' into '-fvtable-verify=preinit' (tcmalloc stuff requires this special flag).
BUG=
TEST=Built Chrome with GYP_DEFINES=use_vtable_verify=1
