PNaCl ABI: Remove use of @llvm.memset.p0i8.i64 (64-bit intrinsic variant)
Convert calls to this intrinsic to use the 32-bit variant instead. Do
the same for the memcpy and memmove intrinsics too.
Change the PNaCl ABI verifier to check this argument.
BUG=https://code.google.com/p/nativeclient/issues/detail?id=3530
TEST=*.ll tests + PNaCl toolchain trybots
