rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is2011-06-18T06:05:24ZChris Lattnersabre@nondot.org2011-06-18T06:05:24Zurn:sha1:b85e4eba85a38698f3b3332f82554bf8442547e2
for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the
target indep prefetch change.
As usual, updating the testsuite is a PITA.

to optionally look for constant or local (alloca) memory.
Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select
and Phi nodes, and to support looking for local memory.
Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that
AliasAnalysis knows all the tricks that it knew.

If a function does a volatile load from a global constant, do not2010-10-30T12:59:44ZDuncan Sandsbaldrick@free.fr2010-10-30T12:59:44Zurn:sha1:ad6f541840015690ad1483821eb9d8e5f7e50442
consider it to be readonly. In fact, don't even consider it to be
readonly if it does a volatile load from an AllocaInst either (it
is debatable as to whether readonly would be correct or not in this
case; play safe for the moment). This fixes PR8279.

I actually checked long ago how useful this is, and it isn't
very: it hardly ever fires in the testsuite, but since Chris
wants it here it is!
