a03159bc35 generalize SmallVector copy ctor, there is no requirement for
the initialization vector to have the same fixed size, just the
same element type.

2e2dab8423 Added support for:
- defm and multiclass
- imbricatable multiline C style comment
- FIXME/TODO highlight in comment
- binary and hexadecimal number
- code using [{ }] is no highlighted as special (perhaps not the best
choice)

39a4281deb Implement a signficant optimization for inline asm:
When choosing between constraints with multiple options,
like "ir", test to see if we can use the 'i' constraint and
go with that if possible.  This produces more optimal ASM in
all cases (sparing a register and an instruction to load it),
and fixes inline asm like this:

void test () {
  asm volatile (" %c0 %1 " : : "imr" (42), "imr"(14));
}

Previously we would dump "42" into a memory location (which
is ok for the 'm' constraint) which would cause a problem
because the 'c' modifier is not valid on memory operands.

Isn't it great how inline asm turns 'missed optimization'
into 'compile failed'??

Incidentally, this was the todo in 
PowerPC/2007-04-24-InlineAsm-I-Modifier.ll

Please do NOT pull this into Tak.

b5bd654163 A few inline asm cleanups:
- Make targetlowering.h fit in 80 cols.
  - Make LowerAsmOperandForConstraint const.
  - Make lowerXConstraint -> LowerXConstraint
  - Make LowerXConstraint return a const char* instead of taking a string byref.

c4b6768db4 Remove the code from CodeGenPrepare that moved getresult instructions
to the block that defines their operands. This doesn't work in the
case that the operand is an invoke, because invoke is a terminator
and must be the last instruction in a block.

Replace it with support in SelectionDAGISel for copying struct values
into sequences of virtual registers.

8c9f6c929a Loosen up an assertion to allow intrinsics. I really have no
idea what this code (findNonImmUse) does, so I'm only guessing 
that this is the right thing.  It would be really really nice
if this had comments and perhaps switched to SmallPtrSet
(hint hint) :)
