0390da8c45 Be more aggressive about removing joined physreg copies. 
When a joined COPY changes subreg liveness, we keep it around as a KILL,
otherwise it is safe to delete.

1067cd1da0 Don't verify LiveVariables if LiveIntervals is available. 
LiveVariables becomes horribly wrong while the coalescer is running, but the
analysis is not zapped until after the coalescer pass has run. This causes tons
of false reports when calling verify form the coalescer.

2ea6a20c07 Add basic verification of LiveIntervals. 
We verify that the LiveInterval is live at uses and defs, and that all
instructions have a SlotIndex.

Stuff we don't check yet:

- Is the LiveInterval minimal?
- Do all defs correspond to instructions or phis?
- Do all defs dominate all their live ranges?
- Are all live ranges continually reachable from their def?

7260387710 Fix memdep's code for reasoning about dependences between two calls. A Ref 
response from getModRefInfo is not useful here. Instead, check for identical
calls only in the NoModRef case.

Reapply r110270, and strengthen it to compensate for the memdep changes.
When both calls are readonly, there is no dependence between them.

fb6af5329d For local variables in functions with a frame pointer, use FP as a base 
register for local access when it's closer to the stack slot being refererenced
than the stack pointer. Make sure to take into account any argument frame
SP adjustments that are in affect at the time.

21e64c3fae Remove double-def checking from MachineVerifier, so a register does not have to 
be killed before being redefined.

These checks are usually disabled, and usually fail when enabled. We de facto
allow live registers to be redefined without a kill, the corresponding
assertions in RegScavenger were removed long ago.
