c40874054e Support for annul/pred and other future flags on op codes.

d43c10b583 Added MachineCodeForInstruction object as an argument to
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.
This simplifies the user's code.

2d906f4550 Changes to allow explicit physical register arguments that have been
preallocated.  While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

83409b0b78 Several bug fixes: globals in call operands were not being pulled out;
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

194a5862e0 Extensive changes to the way code generation occurs for function
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

0fae161230 The actual order of parameters in a 2-reg-immediate assembly instructions is

broken up into their elements.  Too many programs break because of this.

9c38927f33 Because the format of the shift instructions is `shift r, shcnt, r', the
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.

Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.

The other changes are just elimination of unnecessary spaces.

240b6d81b8 Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well.
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.
