stack slots and giving them different PseudoSourceValue's did not fix the
problem of post-alloc scheduling miscompiling llvm itself.
- Apply Dan's conservative workaround by assuming any non fixed stack slots can
alias other memory locations. This means a load from spill slot #1 cannot 
move above a store of spill slot #2. 
- Enable post-alloc scheduling for x86 at optimization leverl Default and above.

in lit.py.  These tests have names like "ValueMapTest/0.Iteration", which broke
when lit.py os.path.join()ed them onto the path and then assumed it could
os.path.split() them back off.  This patch shifts path components from the
testPath to the testName until the testPath exists.

LLVMBuildMalloc was reimplemented but with the bug that it didn't insert the
resulting instruction.

allowing it to simplify the crazy constantexprs in the testcases
down to something sensible.  This allows -std-compile-opts to
completely "devirtualize" the pointers to member functions in
the testcase from PR5176.

Several instances of PluginPriority in a single file most probably signifies a

This will require implementing OptionPreprocessor to forbid invalid invocations
such as 'llvmc -O1 -O2'.
