f4c3a59dba Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses.

b350b76a32 tcl seems to hate |& for some reason.

81e6fbe706 switch this to use fastcc to avoid fpstack traffic on x86-32. Switch to
using the count script instead of wc -l

73a902b228 Mark the SSE and MMX load instructions that
X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.
