d735abe5da GCC: Get everything working with gcc 4.6.1.
And by "everything" I mean all the quick regressions.

401165c778 ARM: Further break up condition code into NZ, C, V bits.
Break up the condition code bits into NZ, C, V registers. These are individually
written and this removes some incorrect dependencies between instructions.

2178859b76 ARM: Break up condition codes into normal flags, saturation, and simd.
This change splits out the condcodes from being one monolithic register
into three blocks that are updated independently. This allows CPUs
to not have to do RMW operations on the flags registers for instructions
that don't write all flags.

adbd84ab9f ARM: The ARM decoder should not panic when decoding undefined holes is arch.
This can abort simulations when the fetch unit runs ahead and speculatively
decodes instructions that are off the execution path.
