1d6a26507b Use TryParseRegister() instead of MatchRegisterName(). The former returns -1 
while the latter doesn't.

5bde734598 fix a bug where we had an implicit assumption that the 
result instruction operand numbering matched the result pattern.

Fixing this allows us to move the xchg/test aliases to the .td file.

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.
[*] It's amazing how often people pass mega-byte long arrays by copy...

1e92ec6886 When passing a huge parameter using the byval mechanism, a long 
sequence of loads and stores was being generated to perform the
copy on the x86 targets if the parameter was less than 4 byte
aligned, causing llc to use up vast amounts of memory and time.
Use a "rep movs" form instead.  PR7170.

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(),

8c42f48d02 Disable fancy splitting during spilling unless -extra-spiller-splits is given. 
This way, InlineSpiller does the same amount of splitting as the standard
spiller. Splitting should really be guided by the register allocator, and
doesn't belong in the spiller at all.

7a25825033 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead,
