Summary:
1. Don't try to copy values to and from the same register class.
2. Replace copies with of registers with immediate values with v_mov/s_mov
instructions.
The main purpose of this change is to make MachineSink do a better job of
determining when it is beneficial to split a critical edge, since the pass
assumes that copies will become move instructions.
This prevents a regression in uniform-cfg.ll if we enable critical edge

Fixed layout of test/ASTMerge.
As outlined in a previous RFC, the test/ASTMerge/Inputs folder is getting full and the tests are starting to become interdependent. This is undesirable because
- it makes it harder to write new tests
- it makes it harder to figure out at a glance what old tests are doing, and
- it adds the risk of breaking one test while changing a different one, because of the interdependencies.
To fix this, according to the conversation in the RFC, I have changed the layout from
a.c
Inputs/a1.c
Inputs/a2.c
to
a/test.c
a/Inputs/a1.c
a/Inputs/a2.c

When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
"Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.

[XRay][compiler-rt] Disable XRay instrumentation of the XRay runtime.
Summary:
Adds a CMake check for whether the compiler used to build the XRay
library supports XRay-instrumentation. If the compiler we're using does
support the `-fxray-instrument` flag (i.e. recently-built Clang), we
define the XRAY_NEVER_INSTRUMENT macro that then makes sure that the
XRay runtime functions never get XRay-instrumented.
This prevents potential weirdness involved with building the XRay
library with a Clang that supports XRay-instrumentation, and is
attempting to XRay-instrument the build of compiler-rt.

[BypassSlowDivision] Handle division by constant numerators better.
Summary:
We don't do BypassSlowDivision when the denominator is a constant, but
we do do it when the numerator is a constant.
This patch makes two related changes to BypassSlowDivision when the
numerator is a constant:
* If the numerator is too large to fit into the bypass width, don't
bypass slow division (because we'll never run the smaller-width
code).
* If we bypass slow division where the numerator is a constant, don't
OR together the numerator and denominator when determining whether
both operands fit within the bypass width. We need to check only the
denominator.

Fix Modi and File count if there are more than 65535 modules/files.
These numbers are intended to be capped at 65535, but
`std::max<uint16_t>(UINT16_MAX, N)` always returns N for any N because
the expression is the same as `std::max((uint16_t)UINT16_MAX, (uint16_t)N)`.

Always use relative jump table encodings on PowerPC64.
For the default, small and medium code model, use the existing
difference from the jump table towards the label. For all other code
models, setup the picbase and use the difference between the picbase and
the block address.
Overall, this results in smaller data tables at the expensive of one or
two more arithmetic operation at the jump site. Given that we only create
jump tables with a lot more than two entries, it is a net win in size.
For larger code models the assumption remains that individual functions
are no larger than 2GB.

General clean up of Mach-O error handling in llvm-objdump.
To get a good error message for all files that could contain Mach-O
files the code in llvm-objdump needs to use the archive member name
and name of the architecture of a slice of a universal file in those cases
where the error come from a Mach-O file in an archive or a universal file.
Most of this is fixed by moving the call to checkSymbolTable() into
ProcessMachO() and calling it when the operation needs the symbol
table. And then calling the form of report_error() that has the
ArchiveName and ArchitectureName arguments. One other place
needed to call this form of report_error() also with these arguments.
Also changed the code in MachODump.cpp to not use report_fatal_error()
and use report_error() instead to make the code smaller and cleaner. All
cases of this are for errors with the symbol table which should now never
be tripped since checkSymbolTable() should be called first to get a good
error message in these cases.
