Matt Arsenault 7cf5581712 Analysis: Update some tests for opaque pointers
StackSafetyAnalysis/lifetime.ll had one bitcast removed that may have
mattered. The concluded lifetime is longer based on the underlying
alloca, instead of the bitcasted pointer so left that as a pointless
cast.

local.ll memintrin.ll needed some manual fixes
