Fix pattern match for movi with 0D result

Patch by Jiangning Liu.

With some test case changes:
- intrinsic test added to the existing /test/CodeGen/AArch64/neon-aba-abd.ll.
- New test cases to cover movi 1D scenario without using the intrinsic in
test/CodeGen/AArch64/neon-mov.ll.

Don't add suffixes for stdcall/fastcall on 64 coff.

This matches the behavior of both msvc and mingw.

[AArch64] Remove q and non-q intrinsic definitions in the NEON scalar reduce
pairwise implementation, using an overloaded definition instead.

[AArch64] Refactor the NEON scalar reduce pairwise intrinsics, so that they use
float/double rather than the vector equivalents when appropriate.

Transforms: Don't create bad branch weights when folding a switch

This avoids creating branch weight metadata of length one when we fold
cases into the default of a switch instruction, which was triggering
an assert.

llvm-cov: Added -a option for block data.

Similar to gcov, llvm-cov will now print out the block count at the end
of each block. Multiple blocks can end on the same line.

One computational difference is by using -a, llvm-cov will no longer
simply add the block counts together to form a line count. Instead, it
will take the maximum of the block counts on that line. This has a
similar effect to what gcov does, but generates more correct counts in
certain scenarios.

Also updated tests.
