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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205541 91177308-0d34-0410-b5e6-96231b3b80d8

Implement sdiv & udiv for <4 x i16> and <8 x i8> NEON vector types. This avoids moving each element to the integer register file and calling __divsi3 etc. on it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125402 91177308-0d34-0410-b5e6-96231b3b80d8

ARM scheduling fix: compute predicated implicit use properly. Minor drive by fix to cleanup latency computation. Calling getOperandLatency with a deliberately incorrect operand index does not give you the latency you want. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158959 91177308-0d34-0410-b5e6-96231b3b80d8
