fbc39d5045 Simplify code a bit, don't go off the end of the block, now that the current 
block we are in might be empty

65cf42d32f We were forgetting to add FP_REG_KILL instructions to basic blocks which will 
eventually get an assignment due to elimination of PHIs.

986618ebc7 Only insert FP_REG_KILL instructions in MachineBasicBlocks that actually 
use FP instructions.  This reduces the number of instructions inserted in
176.gcc (for example) from 58074 to 101 (it doesn't use much FP, which
is typical).  This reduction speeds up the entire code generator.  In the
case of 176.gcc, llc went from taking 31.38s to 24.78s.  The passes that
sped up the most are the register allocator and the 2 live variable analysis
passes, which sped up 2.3, 1.3, and 1.5s respectively.  The asmprinter
pass also sped up because it doesn't print the instructions in comments :)

Note that this patch is likely to expose latent bugs in machine code passes,
because now basicblock can be empty, where they were never empty before.  I
cleaned out regalloclocal, but who knows about linscan :)

890f92328d Move MOTy::UseType enum into MachineOperand. This eliminates the 
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

3f1e8e7ceb Completely rewrite how getelementptr instructions are expanded. This has two 
(minor) benefits right now:

1. An extra dummy MOVrr32 is gone.  This move would often be coallesced by
   both allocators anyway.
2. The code now uses the gep_type_iterator to walk the gep, which should future
   proof it a bit.  It still assumes that array indexes are Longs though.

These don't really justify rewriting the code.  The big benefit will come later
though.

6d2fdcfb8a The two address pass cannot handle two addr instructions where one incoming 
value is a physreg and one is a virtreg.  For this reason, disable copy folding
entirely for physregs.  Also, use the new isMoveInstr target hook which gives us
folding of FP moves as well.

e42cde2a14 Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some 
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less
