e1dde7b05a Replace SplitKit SSA update with an iterative algorithm very similar to the one 
in SSAUpdaterImpl.h

Verifying live intervals revealed that the old method was completely wrong, and
we need an iterative approach to calculating PHI placemant. Fortunately, we have
MachineDominators available, so we don't have to compute that over and over
like SSAUpdaterImpl.h must.

Live-out values are cached between calls to mapValue() and computed in a greedy
way, so most calls will be working with very small block sets.

Thanks to Bob for explaining how this should work.

d68f458244 Make MachineDominators available for SplitEditor. We are going to need it for 
proper SSA updating.

This doesn't cause MachineDominators to be recomputed since we are already
requiring MachineLoopInfo which uses dominators as well.

24a492683c Revert r117582, which reverted r77396. Searching PATH for a string 
which contains slashes is inconsistent with the meaning of PATH on
Unix-type platforms, and pretty surprising.

If the user has given a specific path to execute and we can't
execute it, we should fail and say why.  (Apparently the new
posix_spawn code doesn't always say why, but that's a separate
issue.)

c61c7549a8 Revert r77396. 
Original commit message:

    On "Unix", if Program::FindProgramByName is given a name containing
    slashes, just go with it, regardless of whether it looks like it will
    be executable. This follows the behavior of sh(1) more closely.

It's better when behaviour is consistent between platforms. This change also
makes FindExecutable() behave as expected on unix-likes (before this commit, it
used to always succeed).

0104d9de04 - Assign load / store with shifter op address modes the right itinerary classes. 
- For now, loads of [r, r] addressing mode is the same as the
  [r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
  identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
  is "free".

f20700ca77 SelectionDAG shuffle nodes do not allow operands with different numbers of 
elements than the result vector type.  So, when an instruction like:

%8 = shufflevector <2 x float> %4, <2 x float> %7, <4 x i32> <i32 1, i32 0, i32 3, i32 2>

is translated to a DAG, each operand is changed to a concat_vectors node that appends 2 undef elements.  That is:

shuffle [a,b], [c,d] is changed to:
shuffle [a,b,u,u], [c,d,u,u]

That's probably the right thing for x86 but for NEON, we'd much rather have:

shuffle [a,b,c,d], undef

Teach the DAG combiner how to do that transformation for ARM.  Radar 8597007.

11d03f690e Remove try/catch(...) from Win32/Signals.inc. 
catch(...) is used in Win32/Signals.inc for catching Win32 structured
exceptions, but according to [1], this is wrong.

We can't simply change try/catch to __try/__finally, since this syntax is not
supported by MinGW. We can use __try/__finally on MSVC and __try1/__except1
macros on MinGW [2], but I think that that solution obfuscates the code too
much.

The use of try/catch(...) in Signals.inc makes it impossible to link
MinGW-compiled libSystem with llvm-gcc compiled executables. I propose that we
just remove try/catch(...) from Signals.inc, since the meaning of the code won't
change.

sense, when the instruction takes the 16-bit ax register or m16 memory

505faa6b12 Change v64 datalayout in SPU. 
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

7c730e7790 When the "true" and "false" blocks of a diamond if-conversion are the same, 
do not double-count the duplicate instructions by counting once from the
beginning and again from the end.  Keep track of where the duplicates from
the beginning ended and don't go past that point when counting duplicates
at the end.  Radar 8589805.

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction.  That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.

2ad40d3494 Change if-conversion to keep track of the extra cost due to microcoded 
instructions separately from the count of non-predicated instructions.  The
instruction count is used in places to determine how many instructions to
copy, predicate, etc. and things get confused if that count includes the
extra cost for microcoded ops.
