Dan Gohman aeb5e66772 Reapply r118917. With pseudo-instruction expansion moved to 
a different pass, the complicated interaction between cmov expansion
and fast isel is no longer a concern.

Dan Gohman 8b67c720f2 Split pseudo-instruction expansion into a separate pass, to make it 
easier to debug, and to avoid complications when the CFG changes
in the middle of the instruction selection process.

Jakob Stoklund Olesen 9beef41f2c Fix emergency spilling in LiveIntervals::spillPhysRegAroundRegDefsUses. 
Always spill the full representative register at any point where any subregister
is live.

This fixes PR8620 which caused the old logic to get confused and not spill
anything at all.

The fundamental problem here is that the coalescer is too aggressive about
physical register coalescing. It sometimes makes it impossible to allocate
registers without these emergency spills.

Bob Wilson dfac58bed1 Tidy up some things in <arm_neon.h>. 
Stop defining types with "__neon_" prefixes and then using typedefs without
the prefix; there's no reason to do that anymore.  Remove types that combine
multiple Neon vectors and treat them as a single long vector; they are not
used.

Michael J. Spencer 5ed2428b3c This is the first step in adding sane error handling support to LLVMSystem. 
The system API's will be shifted over to returning an error_code, and returning
other return values as out parameters to the function.

Code that needs to check error conditions will use the errc enum values which
are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are
compatable with the error codes in WinError.h due to some magic in system_error.

An example would be:

if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool.
  handle_error(ec);
}

Duncan Sands 5ffc298bc7 In which I discover the existence of loops. Threading an operation 
over a phi node by applying it to each operand may be wrong if the
operation and the phi node are mutually interdependent (the testcase
has a simple example of this).  So only do this transform if it would
be correct to perform the operation in each predecessor of the block
containing the phi, i.e. if the other operands all dominate the phi.
This should fix the FFMPEG snow.c regression reported by İsmail Dönmez.

Bill Wendling a68e3a5397 Encode the multi-load/store instructions with their respective modes ('ia', 
'db', 'ib', 'da') instead of having that mode as a separate field in the
instruction. It's more convenient for the asm parser and much more readable for
humans.

Jakob Stoklund Olesen e2b8858611 Fix PR8612 in the standard spiller, take two. 
The live range of a register defined by an early clobber starts at the use slot,
not the def slot.

Except when it is an early clobber tied to a use operand. Then it starts at the
def slot like a standard def.
