Change the Opcode enum for PHI nodes from "Instruction::PHINode" to "Instruction::PHI" to be more consistent with the other instructions.

  getelementptr code path for use by other code paths (like malloc and alloca).
* Optimize comparisons with zero
* Generate neg, not, inc, and dec instructions, when possible.

This gives some code size wins, which might translate into performance.  We'll
see tommorow in the nightly tester.

off the bottom of the stack.  This fixes PR#41

llvm-svn: 9114

X86/linux.  :(  The problem is that a signal delivered while the function
is executing could clobber the functions stack.  This is a partial fix
for PR41.
