the X86 does not support a full set of fp cmove instructions, so we can't always
fold the condition into the select.  :(  Yuck.

that require the asmwriter to be extended (printing implicit uses before the
explicit operands)

easily steal it for a separate use in the reoptimizer.

In ReadArchiveBuffer, make sure that MemberName is set in the case where
getObjectType would want to return SVR4LongFilename.

folding compares into the select yet.

pass can eliminate many nasty cases of them, start generating them in the optimizers

an incoming value from a block, the selector would evaluate the constant
at the TOP of the block instead of at the end of the block.  This made the
live range for the constant span the entire block, increasing register
pressure needlessly.

Otherwise, if you're in debugging mode, you get warnings for (apparently)
every immediate constant in the function during reg. allocation.

rid of the funny cast.

#1 is to unconditionally strip constantpointerrefs out of
instruction operands where they are absolutely pointless and inhibit
optimization.  GRRR!

#2 is to implement InstCombine/getelementptr_const.ll
