cast fp->bool
cast ulong->fp
algebraic right shift long by non-constant value
These changes tested across most of the test suite. Fixes Regression/casts

hurt a lot in others. Instead, improve branching version of SetCC and
Select instructions. The old code will be in CVS should we ever need to
dig it up again.

Change int->float cast code to put conversion constants in constant pool.
Shorten code sequence for constant pool fp loads.
Remove LOADLoDirect/LOADLoIndirect psuedo instructions and tweak asmwriter

that have a frame pointer. This change fixes Burg. In addition, make
the necessary changes to floating point code gen and constant loading after
Chris Lattner's fixes to the asm writer. These changes fix MallocBench/gs

Darwin. Also, change asm printer to output proper stubs for external
functions whose address is passed as an argument to aid in bugpointing.

Replace STDX (store 64 bit int indexed) with STFDX (store double indexed)
Fix latent bug in indexed load generation
Generate indexed loads and stores in many more cases

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

* Fn args passed in registers are now recorded as used by the call instruction
`-> asm printer updated to not print out those registers with the call instr
* Stack frame layout in prolog/epilog fixed, spills and vararg fns now work
* float/double to signed int codegen now correct
* various single precision float codegen bugs fixed
* const integer multiply codegen fixed
* select and setcc blocks inserted into the correct place in machine CFG
* load of integer constant code optimized
All of Shootout tests now work. Great thanks to Nate Begeman for the patch!

a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation

The large diff is because of indentation of a whole region
* Fix querying predecessor blocks in SelectPHINodes(), thanks to Brian (v8)
* Add support for external functions malloc() and free()
* Fix some code indentation
Remember, kids: It's not plagiarism if you "creatively borrow" from your
sources. It's called "research"!
