fa27ff296d Kill Target specific ModuleMatchQuality stuff. 
- This was overkill and inconsistently implemented.

d6fd377f33 Simplify JIT target selection. 
- Instead of requiring targets to define a JIT quality match function, we just
   have them specify if they support a JIT.

 - Target selection for the JIT just gets the host triple and looks for the best
   target which matches the triple and has a JIT.

66ac53165e Change Thumb2 jumptable codegen to one that uses two level jumps: 
Before:
      adr r12, #LJTI3_0_0
      ldr pc, [r12, +r0, lsl #2]
LJTI3_0_0:
      .long    LBB3_24
      .long    LBB3_30
      .long    LBB3_31
      .long    LBB3_32

After:
      adr r12, #LJTI3_0_0
      add pc, r12, +r0, lsl #2
LJTI3_0_0:
      b.w    LBB3_24
      b.w    LBB3_30
      b.w    LBB3_31
      b.w    LBB3_32

This has several advantages.
1. This will make it easier to optimize this to a TBB / TBH instruction +
   (smaller) table.
2. This eliminate the need for ugly asm printer hack to force the address
   into thumb addresses (bit 0 is one).
3. Same codegen for pic and non-pic.
4. This eliminate the need to align the table so constantpool island pass
   won't have to over-estimate the size.

Based on my calculation, the later is probably slightly faster as well since
ldr pc with shifter address is very slow. That is, it should be a win as long
as the HW implementation can do a reasonable job of branch predict the second
branch.

ce63ffb52f More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

81c102ba66 Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address. 
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

b8158acc23 Reapply my previous asmprinter changes now with more testing and two 
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

446c428bf3 Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically. 
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.

dda0f4cb79 - Add some NEON ld / st instruction static encoding. 
- Make bits 25-27 for ldrh, etc. explicitly zero. Previously only the JIT uses the encoding information and it's assuming anything not specified to be zero. Making them explicit so the disassembler is happy.
Patch by Sean Callanan.

6b61cd185e Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed arguments in a vararg call. 
With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put 
into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack.

The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list.
