a55661b6bd Enable MachO writing for ARM/Darwin. Lots of stuff still doesn't work
(relocations, e.g.), but this will allow simple things to flow through.

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(),

1e96bab329 In the calling convention logic, ValVT is always a legal type,
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

c07bd40a64 partition operand processing between aliases and instructions.
Right now the code is partitioned but the behavior is the same.
This should be improved in the near future.   This removes some
uses of TheOperandList.

1d13bda737 take a big step to making aliases more general and less of a hack:
now matchables contain an explicit list of how to populate each
operand in the result instruction instead of having them somehow
magically be correlated to the input inst.

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,
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with

1440e8b918 Inside the calling convention logic LocVT is always a simple
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.
