7365c091f9 Remove IntrWriteMem, as it's the default. Rename IntrWriteArgMem 
to IntrReadWriteArgMem, as it's for reading as well as writing.

130073904f Implement AccessesArguments checking in the two-callsite form 
of BasicAA::getModRefInfo. This allows BasicAA to say that two
memset calls to non-aliasing memory locations don't interfere.

1fe9c34d3f 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?

5fa417c790 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.

e3ede5e2e4 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.

73cf709a08 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.
