Various updates suggested by Misha and Chris. Moved material that is
aimed more at the comiler writer than the llvmc user later in the document.

First version of a manual page for the llvmc compiler driver. This tool is
being documented before being written to foster discussion about what the
tool should do. Eventually, we'll achieve a decision point at which time
this document forms the requirements for the tool from which it will be
coded.

Changes commited for Nate Begeman:

Use a PowerPC specific prolog epilog inserter to control where spilled
callee save regs are placed on the stack.
Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access
globals

Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp
