* Multiplications by 2^X are turned into shifts. This factors code out of the 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9267 91177308-0d34-0410-b5e6-96231b3b80d8
