dcfc3c580e In InsertProfilingInitCall(), make it legal to pass in a null array, in 
which case you'll get a null array and zero passed to the profiling function.

769668c09a 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.

9b53c7c797 Fix a major pessimization in the instcombiner. If an allocation instruction 
is only used by a cast, and the casted type is the same size as the original
allocation, it would eliminate the cast by folding it into the allocation.

Unfortunately, it was placing the new allocation instruction right before
the cast, which could pull (for example) alloca instructions into the body
of a function.  This turns statically allocatable allocas into expensive
dynamically allocated allocas, which is bad bad bad.

This fixes the problem by placing the new allocation instruction at the same
place the old one was, duh. :)

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...
