d76041cf58 Add a -regalloc=default option that chooses a register allocator based on the -O
optimization level.

This only really affects llc for now because both the llvm-gcc and clang front
ends override the default register allocator. I intend to remove that code later.

The goal is to match following 3 lines. In otherwords, a temp. label between to DEBUG_VALUE comments.
        ;DEBUG_VALUE: bar:x <- undef   ## 2010-01-18-Inlined-Debug.c:7
Ltmp1:
        ;DEBUG_VALUE: foo:__x <- undef ## 2010-01-18-Inlined-Debug.c:5

392dd2b35f Changed the encoding of X86 floating point stack operations where both operands
are st(0).  These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0.  To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used.  To do this the same logical trick is use from the darwin assembler
in converting things like this:

fmul %st(0), %st

into this:

fmul %st(0)

by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand.  This also has the add
benefit to allow things like:

fmul %st(1), %st

that llvm-mc did not assemble.

c71b7c8c61 Thumb2 RSBS instructions were being printed without the 'S' suffix.
Fix it by changing the T2I_rbin_s_is multiclass to handle the CPSR
output and 'S' suffix in the same way as T2I_bin_s_irs.
