bfb4fe5109 Make RequiresFPRegKill() take a MachineBasicBlock arg.
In InsertFPRegKills(), just check the MachineBasicBlock for successors
instead of its corresponding BasicBlock.

74ed24c9de In InsertFPRegKills(), use the machine-CFG itself rather than the
LLVM CFG when trying to find the successors of BB.

a36743c473 Add MRegisterInfo subclass for the SparcV9 target (containing only stub
functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.

The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.

7fba37bb96 Merge TargetRegInfo.h into SparcV9RegInfo.h, which is its only subclass.
This prepares us to be able to de-virtualize and de-abstract it, and
take the register allocator bits out and move them into the register allocator
proper...

1b07a2282a Include SparcV9RegInfo.h instead of TargetRegInfo.h. This serves as a bit of
documentation that this module needs to be made independent of the
register file description of the current target.

96889991bb Go back to the interpreter main loop after performing intrinsic lowering,
because 1) the first instruction might not be a call site, and
2) CS and SF.Caller were not getting set to point to the new call site
anyway (resulting in a crash on e.g. call %llvm.memset).

should be harmless.)

1dc8e19185 Clarify the logic: the flag is renamed to `deleteFn' to signify it will delete
the function instead of isolating it. This also means the condition is reversed.

d1906e2ace Implement a todo, rewriting all possible scev expressions inside of the

not clear that this will be a performance win overall.  Tommorows test
results will tell. :)
