Patch to fix PR337. Make sure to mark all aliased physical registers as used

when we see a read of a register. This is important in cases like:
AL = ...
AH = ...
= AX
The read of AX must make both the AL and AH defs live until the use.

Stop LiveVariables from using BasicBlocks as part of the mapping, instead

use MachineBasicBlocks. To do this, we traverse the Machine CFG instead of
the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of
indirections and mappings.
