eaa8b1f81d Add a pass to do call graph analyis to overlay the autos and frame sections of 
leaf functions. This pass will be extended to color other nodes of the call tree 
as well in future.

eb01abaad1 Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

over absolute addressing even in non-PIC mode (unless the address
has an index or something else incompatible), because it has a

the VEXT shuffles during legalization and lower them to a target-specific
DAG node.

c0823fe7c6 Simplify RegScavenger::FindUnusedReg. 
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

5cfd4ddece PowerPC inline asm was emitting two output operands 
for a single "m" constraint; this is wrong because the
opcode of a load or store would have to change in parallel.
This patch makes it always compute addresses into a register,
which is correct but not as efficient as possible.  7144566.
