PNaCl: Disable parts of InstCombine that introduce *.with.overflow intrinsics
Change the PNaCl ABI checker to disallow these intrinsics.
Note that I had originally intended to commit this before my earlier
change (https://codereview.chromium.org/15688011) that enables the
ExpandArithWithOverflow pass. Enabling ExpandArithWithOverflow
without changing InstCombine causes ExpandArithWithOverflow to fail on
some of the *.with.overflow intrinsic calls that InstCombine
introduces. This change therefore fixes some breakage.
BUG=https://code.google.com/p/nativeclient/issues/detail?id=3434
TEST=PNaCl toolchain trybots + GCC torture tests + LLVM test suite
