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 :)

Completely rewrite how getelementptr instructions are expanded. This has two

1. An extra dummy MOVrr32 is gone. This move would often be coallesced by

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.

Too many changes in one commit:
1. LiveIntervals now implement a 4 slot per instruction model. Load,
Use, Def and a Store slot. This is required in order to correctly
represent caller saved register clobbering on function calls,
register reuse in the same instruction (def resues last use) and
also spill code added later by the allocator. The previous
representation (2 slots per instruction) was insufficient and as a
result was causing subtle bugs.
2. Fixes in spill code generation. This was the major cause of
failures in the test suite.
3. Linear scan now has core support for folding memory operands. This
is untested and not enabled (the live interval update function does
not attempt to fold loads/stores in instructions).
4. Lots of improvements in the debugging output of both live intervals
and linear scan. Give it a try... it is beautiful :-)
In summary the above fixes all the issues with the recent reserved
register elimination changes and get the allocator very close to the
next big step: folding memory operands.
