8ab5fe574a Switch the PPC backend over to using FORMAL_ARGUMENTS for formal argument 
handling.  This makes the lower argument code significantly simpler (we
only need to handle legal argument types).

Incidentally, this also implements support for vector argument registers,
so long as they are not on the stack.

0949ed5412 Fix PowerPC/2006-05-12-rlwimi-crash.ll 
Nate, please verify that if InsertMask is 0, rlwimi shouldn't be used.
This fixes the crash and causes no PPC testsuite regressions.

e45aa737ba Revert Nate's CR patch from last night, which caused many regressions (e.g. fhourstones). 
Loading and storing off R0 isn't what we wanted.  Also, taking some CR's out of
CRRC seems to cause failures as well.  Further investigation is required.

b4432f3d47 Suck block address tracking out of targets into the JIT Emitter. This 
simplifies the MachineCodeEmitter interface just a little bit and makes
BasicBlocks work like constant pools and jump tables.

f75f9be3fb Several related changes: 
1. Change several methods in the MachineCodeEmitter class to be pure virtual.
2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them
   from the MachineCodeEmitter interface, and reducing the amount of target-
   specific code.
3. Change the JITEmitter so that it allocates constantpools and jump tables
   *right* next to the functions that they belong to, instead of in a separate
   pool of memory.  This makes all memory for a function be contiguous, and
   means the JITEmitter only tracks one block of memory now.

d3f0aefc33 Fix a purely hypothetical problem (for now): emitWord emits in the host 
byte format.  This doesn't work when using the code emitter in a cross target
environment.  Since the code emitter is only really used by the JIT, this
isn't a current problem, but if we ever start emitting .o files, it would be.

43b429b059 Refactor the machine code emitter interface to pull the pointers for the current 
code emission location into the base class, instead of being in the derived classes.

This change means that low-level methods like emitByte/emitWord now are no longer
virtual (yaay for speed), and we now have a framework to support growable code
segments.  This implements feature request #1 of PR469.

37efe67645 JumpTable support! What this represents is working asm and jit support for

PIC, and less dense forms of jump tables.
