51b0cac238 Change "value" in MachineOperand to be a GlobalValue, as that is the only 
thing that can be in it.  Remove a dead method.

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.

9ee2fec714 For PR764: 
Don't check in the LibDeps.txt and FinalLibDeps.txt files to CVS because
the content differs from platform to platform. Instead, adjust the makefile
so that a dummy llvm-config is built if Perl is not available.

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.

95a4f191e0 Finish up the initial jump table implementation by allowing jump tables to 
not be 100% dense.  Increase the minimum threshold for the number of cases
in a switch statement from 4 to 6 in order to create a jump table.

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.

055baf5c7b 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.
