679cbd3b21 Add support for a few simple fixups to the ARM Darwin asm backend. This allows 
constant pool references and global variable refernces to resolve properly
for object file generation. For example,

int x;
void foo(unsigned a, unsigned *p) {
  p[a] = x;
}

can now be successfully compiled directly to an (ARM mode) object file.

e25e1ef48b Speed up AddSectionToTheEnd. It was walking all fragments in all sections. 
This is really slow with we have 1000s of sections each with a corresponding
relocation section. Also, it is only used by the ELF writer to add
basic data, so there is no need to force a new layout pass.

Should fix PR8563.

e717610f53 Add support for parsing register lists. We can't use a bitfield to keep track of 
the registers, because the register numbers may be much greater than the number
of bits available in the machine's register.

I extracted the register list verification code out of the actual parsing of the
registers. This made checking for errors much easier. It also limits the number
of warnings that would be emitted for cascading infractions.

db28788e4a go to great lengths to work around a GAS bug my previous patch 
exposed:

GAS doesn't accept "fcomip %st(1)", it requires "fcomip %st(1), %st(0)"
even though st(0) is implicit in all other fp stack instructions.

Fortunately, there is an alias for fcomip named "fcompi" and gas does
accept the default argument for the alias (boggle!).

As such, switch the canonical form of this instruction to "pi" instead
of "ip".  This makes the code generator and disassembler generate pi,
avoiding the gas bug.

8c24b0c699 rework the rotate-by-1 instructions to be defined like the 
shift-by-1 instructions, where the asmstring doesn't contain
the implicit 1.  It turns out that a bunch of these rotate
instructions were completely broken because they used 1 
instead of $1.

This fixes assembly mismatches on "rclb	$1, %bl" and friends,
where we used to generate the 3 byte form, we now generate the
proper 2-byte form.

fb7000fcbd correct suffix matching to search for s/l/t suffixes on 
floating point stack instructions instead of looking for b/w/l/q.

This fixes issues where we'd accidentally match fistp to fistpl,
when it is in fact an ambiguous instruction.

This changes the behavior of llvm-mc to reject fstp, which was the
correct fix for rdar://8456389:
t.s:1:1: error: ambiguous instructions require an explicit suffix (could be 'fstps', 'fstpl', or 'fstpt')
fstp	(%rax)

it also causes us to correctly reject fistp and fist, which addresses
PR8528:

t.s:2:1: error: ambiguous instructions require an explicit suffix (could be 'fistps', or 'fistpl')
fistp (%rax)
^
t.s:3:1: error: ambiguous instructions require an explicit suffix (could be 'fists', or 'fistl')
fist (%rax)
^

Thanks to Ismail Donmez for tracking down the issue here!

662e5a30e8 Reimplement BuildResultOperands to be in terms of the result instruction's 
operand list instead of the operand list redundantly declared on the alias
or instruction.

With this change, we finally remove the ins/outs list on the alias.  Before:
  def : InstAlias<(outs GR16:$dst), (ins GR8 :$src),
                  "movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;
After:
  def : InstAlias<"movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;

This also makes the alias mechanism more general and powerful, which will
be exploited in subsequent patches.

69300a2f47 When passing a parameter using the 'byval' mechanism, inline code needs to be used 
to perform the copy, which may be of lots of memory [*].  It would be good if the
fall-back code generated something reasonable, i.e. did the copy in a loop, rather
than vast numbers of loads and stores.  Add a note about this.  Currently target
specific code seems to always kick in so this is more of a theoretical issue rather
than a practical one now that X86 has been fixed.

35fcd6557f Introduce DIBuilder. It is intended to be a front-end friendly interface to emit debuggging information entries in LLVM IR. 
To create debugging information for a pointer, using DIBUilder front-end just needs
	DBuilder.CreatePointerType(Ty, Size);
instead of
	DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type,
                                       TheCU, "", getOrCreateMainFile(),

92b5a2eb16 The MC code couldn't handle ARM LDR instructions with negative offsets: 
vldr.64 d1, [r0, #-32]

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

8239daf7c8 Two sets of changes. Sorry they are intermingled. 
1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to
   "optimize for latency". Call instructions don't have the right latency and
   this is more likely to use introduce spills.
2. Fix if-converter cost function. For ARM, it should use instruction latencies,
   not # of micro-ops since multi-latency instructions is completely executed
   even when the predicate is false. Also, some instruction will be "slower"
   when they are predicated due to the register def becoming implicit input.

a1ca91af4e Completely reject instructions that have an operand in their

the asmmatcher would just force a 0 register into it, which clearly
isn't right.  Mark a bunch of ARM instructions that use this as 
isCodeGenOnly.  Some of them are clearly pseudo instructions (like
t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will
either need to be removed or the asmmatcher will need to be taught
about it (someday).

with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.
