[ARM64] Fix 'assert("...")' to be 'assert(0 && "...")'. Otherwise, it is
no assert at all. ;] Some of these should probably be switched to
llvm_unreachable, but I didn't want to perturb the behavior in this
patch.

Found by -Wstring-conversion, which I'll try to turn on in CMake builds
at least as it is finding useful things.

Recommitted fix for PR18931, with extended tests set.
Issue subject: Crash using integrated assembler with immediate arithmetic

Fix description:
Expressions like 'cmp r0, #(l1 - l2) >> 3' could not be evaluated on asm parsing stage,
since it is impossible to resolve labels on this stage. In the end of stage we still have
expression (MCExpr).
Then, when we want to encode it, we expect it to be an immediate, but it still an expression.
Patch introduces a Fixup (MCFixup instance), that is processed after main encoding stage.

[PowerPC] VSX instruction latency corrections

The vector divide and sqrt instructions have high latencies, and the scalar
comparisons are like all of the others. On the P7, permutations take an extra
cycle over purely-simple vector ops.

llvm-mc: Fix build breakage caused by r205050.

When LLVM is not built with zlib, nocompression.s will test
for the error message.  But this test case will cause breakage
because the exit code is non-zero.  This commit fix this issue
by adding "not" to the command.

[PowerPC] Handle v2i64 comparisons

v2i64 is a legal type under VSX, however we don't have native vector
comparisons. We can handle eq/ne by casting it to an Altivec type, but
everything else must be expanded.

Detemplatize LOHDirective.

The ARM64 backend uses it only as a container to keep an MCLOHType and
Arguments around so give it its own little copy. The other functionality
isn't used and we had a crazy method specialization hack in place to
keep it working. Unfortunately that was incompatible with MSVC.

Also range-ify a couple of loops while at it.

Support: normalize the default triple on Unix

This will fix cross-compiling buildbots (e.g. cygwin).  This is in the same vein
as SVN r205070.  Apply this to fix the cross-compiling scenario, even though the
preferred solution is to update the build system to normalize the embedded
triple rather than perform this at runtime every time.  This is meant to tide us
over until that approach is fleshed out and applied.

Add a missing break.

Patch by Tobias Güntner.

I tried to write a test, but the only difference is the Changed value that
gets returned. It can be tested with "opt -debug-pass=Executions -functionattrs,
but that doesn't seem worth it.
