6e7961be11 Ignore NumberHack and give each SubRegIndex instance a unique enum value instead. 
This passes lit tests, but I'll give it a go through the buildbots to smoke out
any remaining places that depend on the old SubRegIndex numbering.

Then I'll remove NumberHack entirely.

201408751f Use enums instead of literals for X86 subregisters. 
The cases in getMatchingSuperRegClass cannot be broken up until the enums have
unique values.

bcd0854609 Allow t2MOVsrl_flag and t2MOVsra_flag instructions to be predicated. 
I don't know of any particular reason why that would be important, but
neither can I see any reason to disallow it.

c8bea44d68 Fix up instruction classes for Thumb2 RSB instructions to be consistent with 
Thumb2 ADD and SUB instructions: allow RSB instructions be changed to set the
condition codes, and allow RSBS instructions to be predicated.

3a19b732d8 Replace the tablegen RegisterClass field SubRegClassList with an alist-like data 
structure that represents a mapping without any dependencies on SubRegIndex
numbering.

This brings us closer to being able to remove the explicit SubRegIndex
numbering, and it is now possible to specify any mapping without inventing
*_INVALID register classes.

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.

f2bec8edf6 Apply timeouts and memory limits in more places. In particular, when 
bugpoint does "Running the code generator to test for a crash" this
gets you a crash if llc goes into an infinite loop or uses up vast
amounts of memory.

50265dbaf0 MC/X86: Subdivide immediates a bit more, so that we properly recognize immediates based on the width of the target instruction. For example: 
addw $0xFFFF, %ax
should match the same as
  addw $-1, %ax
but we used to match it to the longer encoding.

b8ebb375b6 Recognize more BUILD_VECTORs and VECTOR_SHUFFLEs that can be implemented by 
copying VFP subregs.  This exposed a bunch of dead code in the *spill-q.ll
tests, so I tweaked those tests to keep that code from being optimized away.
