7e7f06e70a X86FastISel support for loading and storing values of type i1.

cbbea0ffc7 Expand i8 selects into control flow instead of 16-bit conditional 
moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.

31fb12f93a Remove unneeded ARM-specific DAG nodes for VLD* and VST* Neon operations. 
The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.

af70e5c676 Don't use INSERT_SUBREG to model anyext operations on x86-64, as it 
leads to partial-register definitions. To help avoid redundant
zero-extensions, also teach the h-register matching patterns that
use movzbl to match anyext as well as zext.

code hints that it would be a good idea to inline
a function ("inline" keyword).  No functional change
yet; FEs do not emit this and inliner does not use it.

2a610c7387 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

a60e51f7e8 Make linkerprivate work for ARM and PPC. Testcase covers 
all Darwin targets; could be split into separate tests for
the chip subdirectories, but from Chris' last mail on testing
I assume he'd rather have only one test.  Generic seems to be
the best available, maybe there should be a Darwin subdirectory?

eb01abaad1 Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

3f5bb168bc An overhaul of the exception handling code. This is arguably more correct than 
what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.

I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)

088880cb19 Change allowsUnalignedMemoryAccesses to take type argument since some targets 
support unaligned mem access only for certain types. (Should it be size
instead?)

ARM v7 supports unaligned access for i16 and i32, some v6 variants support it
as well.

c22e0b2443 Update llvm-mc / MCAsmStreamer to print the instruction using the actual target 
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets

character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

7417b761c2 Add 'isCodeGenOnly' bit to Instruction .td records. 
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

used to strip hard coded comments out of .td assembly strings.

825b72b057 Split EVT into MVT and EVT, the former representing _just_ a primitive type, while 
the latter is capable of representing either a primitive or an extended type.

LLVMTargetMachine ctor.  It is currently unused.

92319e2454 now that JumpTableDirective can differentate picness itself, MIPS TAI 
no longer needs a targetmachine to initialize itself.

dfab291702 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC 
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.

3108222c2c Simplify this code. The case where one class is GR64RegClass and the 
other is a subclass of it is effectively handled by the prior tests.

3a21425dbe Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to 
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.
