Add new debug kind LocTrackingOnly.

Summary:
This new debug emission kind supports emitting line location
information in all instructions, but stops code generation
from emitting debug info to the final output.

This mode is useful when the backend wants to track source
locations during code generation, but it does not want to
produce debug info. This is currently used by optimization
remarks (-pass-remarks, -pass-remarks-missed and
-pass-remarks-analysis).

To prevent debug info emission, DIBuilder never inserts the
annotation 'llvm.dbg.cu' when LocTrackingOnly is enabled.

Fix test case in r211605/r211533

The test case in
"Fix PR20056: Implement pseudo LDR <reg>, =<literal/label> for AArch64" should
only work with Linux.

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction)

PR20071 identifies a problem in PowerPC's fast-isel implementation for
floating-point conversion to integer.  The fctiduz instruction was added in
Power ISA 2.06 (i.e., Power7 and later).  However, this instruction is being
generated regardless of which 64-bit PowerPC target is selected.

The intent is for fast-isel to punt to DAG selection when this instruction is
not available.  This patch implements that change.  For testing purposes, the
existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests
for the expected code generation.  Additionally, the existing test
fast-isel-conversion-p5.ll was found to be incorrectly expecting the
unavailable instruction to be generated.  I've removed these test variants
since we have adequate coverage in fast-isel-conversion.ll.

Fix up scoping in a few tests (and delete one that validates unnecessary behavior).

Most of this is just tests that were silently succeeding in spite of
schema changes I made over a year ago. Cleaning them up as they lead to
failures in a change I'm working on/will come soon.

test/DebugInfo/2010-01-19-DbgScope.ll was removed as it tested miscoping
where a DebugLoc described a location not in the current function. The
test case doesn't describe why this is a valid situation and should be
supported, so I'm removing it and shortly going to commit changes that
make this firmly unsupported/assert-fail.

R600: Fix inconsistency in rsq instructions.

R600 was using a clamped version of rsq, but SI was not. Add a
new rsq_clamped intrinsic and use them consistently.

It's unclear to me from the documentation what behavior
the R600 instructions have, so I assume they have the legacy behavior
described by the SI documents. For R600, use RECIPSQRT_IEEE
for both llvm.AMDGPU.rsq.legacy and llvm.AMDGPU.rsq. R600 also
has RECIPSQRT_FF, which I'm not sure how it fits in here.

Print a=b as an assignment.

In assembly the expression a=b is parsed as an assignment, so it should be
printed as one.

This remove a truly horrible hack for producing a label with "a=.". It would
be used by codegen but would never be reached by the asm parser. Sorry I
missed this when it was first committed.

R600/SI: Use a ComplexPattern for MUBUF stores

Now that non-leaf ComplexPatterns are allowed we can fold all the MUBUF
store patterns into the instruction definition.  We will also be able to
reuse this new ComplexPattern for MUBUF loads and atomic operations.
