8977d087c6 Factor commonality in triple match routines into helper template for registering
classes, and migrate existing targets over.

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

b4fc419d83 this is (unfortunately) several changes mixed together:
1. Spell SectionFlags::Writeable as "Writable".
2. Add predicates for deriving SectionFlags from SectionKinds.
3. Sink ELF-specific getSectionPrefixForUniqueGlobal impl into
   ELFTargetAsmInfo.
4. Fix SectionFlagsForGlobal to know that BSS/ThreadBSS has the
   BSS bit set (the real fix for PR4619).
5. Fix isSuitableForBSS to not put globals with explicit sections
   set in BSS (which was the reason #4 wasn't fixed earlier).
6. Remove my previous hack for PR4619.

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.

3d10a5a757 Add plumbing for the `linker_private' linkage type. This type is meant for
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

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

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.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE.

LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

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.

20c568f366 Add an "alignment" field to the MachineFunction object. It makes more sense to
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

like.
