3005d6bf9f isTriviallyReMaterializable checks the 
TargetInstrDesc::isRematerializable flag, so it isn't necessary to do
this check in its callers.

f2ae9c6220 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons 
when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.

10c870b46f When considering whether to inline Callee into Caller, 
and that will make Caller too big to inline, see if it
might be better to inline Caller into its callers instead.
This situation is described in PR 2973, although I haven't
tried the specific case in SPASS.

d47d348cdf It's possible for a global variable to be optimized out of a metadata object. So 
we should allow a "null" with this dyn_cast.
