AArch64 & ARM: refactor crypto intrinsics to take scalars

Some of the SHA instructions take a scalar i32 as one argument (largely because
they work on 160-bit hash fragments). This wasn't reflected in the IR
previously, with ARM and AArch64 choosing different types (<4 x i32> and <1 x
i32> respectively) which was ugly.

This makes all the affected intrinsics take a uniform "i32", allowing them to
become non-polymorphic at the same time.

inalloca: Don't remove dead arguments in the presence of inalloca args

It disturbs the layout of the parameters in memory and registers,
leading to problems in the backend.

The plan for optimizing internal inalloca functions going forward is to
essentially SROA the argument memory and demote any captured arguments
(things that aren't trivially written by a load or store) to an indirect
pointer to a static alloca.

DIBuilder: simplify array generation to produce true zero-length arrays

For some anachronistic reason we were producing {i32 0} for zero-length
debug info arrays.

(this change is paired with a Clang change and may cause temporary
buildbot noise)

Let's not.

Self-memcpy-elision and memcpy of constant byte to memset transforms don't care how many bytes you were trying to transfer. Sink that safety test after those transforms. Noticed by inspection.

Revert r200150, "[CMake] tablegen(): Use -I <dir> according to the list by include_directories()."

It missed include/llvm/Target. Could I avoid GLOB_RECURSE anyways? :(
FYI, I intended to prune ${LLVM_MAIN_INCLUDE_DIR} in TableGen.cmake in r200150.

DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0}

A bunch of test cases needed to be cleaned up for this, many my fault -
when implementid imported modules I updated test cases by simply
duplicating the prior metadata field - which wasn't always the empty
metadata entry.

Revert: ARM: Enable use of relocation type tlsldo in debug info for tls data.

There seems to be a new problem with the debug info in the test case.
I'll have to investigate this.

When gcov is run without gcda data, it acts as if the counts are all

Also add a pattern for (fneg (fabs ...)).
