9543849102 * Speed up canUseAsImmediateForOpcode() by comparing Operand before
dyn_cast<>ing and checking Constant's value
* Convert tabs to spaces

b77bda4432 * Further cleanup.
* Test for whether bits are shifted out during the optzn.

If so, the fold is illegal, though it can be handled explicitly for setne/seteq

This fixes the miscompilation of 254.gap last night, which was a latent bug
exposed by other optimizer improvements.

64f203922d * Fix printing of signed immediate values
* Generation of opcodes that take 16 bit immediates
* Rewrote multiply to be correct for 64 bit values
* Rewrote all the long handling to be correct for PowerPC
* Fix visitSelectInst() to define the upper register of the pair of regs
  representing a long value
