Fairly major overhaul of MachineInstr & Operand classes
...
- Inline methods that are mostly a single line anyway
- Eliminate several methods that were never called
- Group methods a bit more consistently

- Two minor improvements to the MachineInstr class to reduce footprint and

overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
bitvector. Sped up LLC a little less than 10% in a debug build!

Significant improvement: GEP used by a load or store no longer generates
...
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).
