Saleem Abdulrasool 7258735fa0 ARM: fixup more tests to specify the target more explicitly 
This changes the tests that were targeting ARM EABI to explicitly specify the
environment rather than relying on the default.  This breaks with the new
Windows on ARM support when running the tests on Windows where the default
environment is no longer EABI.

Take the opportunity to avoid a pointless redirect (helps when trying to debug
with providing a command line invocation which can be copy and pasted) and
removing a few greps in favour of FileCheck.

Stephen Lin f799e3f944 Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. 
This was done with the following sed invocation to catch label lines demarking function boundaries:
    sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll
which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct.

Jim Grosbach 24e102a947 ARM: Improve codegen for generic vselect. 
Fall back to by-element insert rather than building it up on the stack.

Jim Grosbach 3e2c6f380c ARM VLDR/VSTR instructions don't need a size suffix. 
Canonicallize on the non-suffixed form, but continue to accept assembly that
has any correctly sized type suffix.

Bill Wendling e1fd78f2bc Generate a VTBL instruction instead of a series of loads and stores when we 
can. As Nate pointed out, VTBL isn't super performant, but it *has* to be better
than this:

_shuf:
@ BB#0:       @ %entry
  push        {r4, r7, lr}
  add         r7, sp, #4
  sub         sp, #12
  mov         r4, sp
  bic         r4, r4, #7
  mov         sp, r4
  mov         r2, sp
  vmov        d16, r0, r1
  orr         r0, r2, #6
  orr         r3, r2, #7

  vst1.8      {d16[5]}, [r0]
  subs        r4, r7, #4
  orr         r0, r2, #5

  orr         r0, r2, #2
  vst1.8      {d16[2]}, [r0]
  orr         r0, r2, #1
  vst1.8      {d16[1]}, [r0]
  vst1.8      {d16[3]}, [r2]
  vldr.64     d16, [sp]
  vmov        r0, r1, d16
  mov         sp, r4
  pop         {r4, r7, pc}

The "illegal" testcase in vext.ll is no longer illegal.

Rafael Espindola 29dda21e96 Remove arm_apcscc from the test files. It is the default and doing this 
matches what llvm-gcc and clang now produce.

Bob Wilson 32cd8550ce Add support for Neon VEXT (vector extract) shuffles. 
This is derived from a patch by Anton Korzh.  I modified it to recognize
the VEXT shuffles during legalization and lower them to a target-specific
DAG node.
