52c61ec164 When using ADDri to get the address of a stack object, 255 is a conservative 
limit on the offset that can be materialized without using the register
scavenger.

0d8ba3303b Treat the ARM inline asm {cc} constraint as a physreg (%CPSR), just like X86 
does for {flags}. If we create virtual registers of the CCR class, RegAllocFast
may try to spill them, and we can't do that.
