Migrate _chk call lowering from SimplifyLibCalls to InstCombine. Stub2010-03-06T10:50:38ZEric Christopherechristo@apple.com2010-03-06T10:50:38Zurn:sha1:27ceaa13f820e33c44e29adc2095dd3e1e69d09f
out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

Log:
Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.
Modified:
llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp
llvm/trunk/test/Transforms/InstCombine/objsize.ll
It appears to be causing swb and nightly test failures.

Fix PR6503. This turned into a much more interesting and nasty bug. Various 2010-03-05T08:46:26ZChris Lattnersabre@nondot.org2010-03-05T08:46:26Zurn:sha1:f34f48c57870cf4eb4d48e23b11e29b95d1950c3
parts of the cmp|cmp and cmp&cmp folding logic wasn't prepared for vectors
(unrelated to the bug but noticed while in the code) and the code was
*definitely* not safe to use by the (cast icmp)|(cast icmp) handling logic
that I added in r95855. Fix all this up by changing the various routines
to more consistently use IRBuilder and not pass in the I which had the wrong
type.
