3fc5b01d38 disable MaskedValueIsZero, ComputeMaskedBits, and SimplifyDemandedBits for
i128 integers.  The 64-bit masks are not wide enough to represent the results.
These should be converted to APInt someday.

_t4:
        fmul f0, f3, f4
        fmadd f1, f1, f2, f0

instead of:

0ff3ca4f92 More DWARF-related things cleanup:
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.
