2208c3214c Make PPC call lowering more aggressive, making the isel matching code simple 
enough to be autogenerated.

03c70b7f27 Switch PPC over to a call-selection model where the lowering code creates 
the copyto/fromregs instead of making the PPCISD::CALL selection code create
them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.

348883611c 3 changes, 2 of which are cleanup one of which changes codegen: 
1. Rearrange code a bit so that the special case doesn't require indenting lots
   of code.
2. Add comments describing PPC calling convention.
3. Only round up to 56-bytes of stack space for an outgoing call if the callee
   is varargs.  This saves a bit of stack space.

b5271a0f4c Instead of implementing LowerCallTo directly, let the default impl produce an 
ISD::CALL node, then custom lower that.  This means that we only have to handle
LEGAL call operands/results, not every possible type.  This allows us to
simplify the call code, shrinking it by about 1/3.

0a12e343e2 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.

bcd2c4f32d Fix PowerPC/2006-05-12-rlwimi-crash.ll

TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

dc94b738d0 New rlwimi implementation, which is superior to the old one. There are 
still a couple missed optimizations, but we now generate all the possible
rlwimis for multiple inserts into the same bitfield.  More regression tests
to come.

20affbd29a 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.

d36b66d6dc 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.

71bc529dfa Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

2bf37af52d 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.

d100478886 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.
