There are problems exposing the _Float16 type on architectures that
haven't defined the ABI/ISel for the type yet, so we're temporarily
disabling the type and making it opt-in.

Summary:
D57116 fails on the armv7 bots, which is I assume due to the timing of
the RSS check on the platform. While I don't have a platform to test
that change on, I assume this would do.

The test could be made more reliable by either delaying more the
allocations, or allocating more large-chunks, but both those options
have a somewhat non negligible impact (more memory used, longer test).

Hence me trying to keep the additional sleeping/allocating to a
minimum.

declaration in MSVCCompat mode

Microsoft compiler permits the use of 'static' storage specifier outside
of a class definition if it's on an out-of-line member function template
declaration.

This patch allows 'static' storage specifier on an out-of-line member
function template declaration with a warning in Clang (To be compatible
with Microsoft).

Intel C/C++ compiler allows the 'static' keyword with a warning in
Microsoft mode. GCC allows this with -fpermissive.

This seems unnecessarily complicated because we gave names to
opposite polarity bools and have code comments that don't really
line up with the logic. 

Step 1: remove UndefUpper and assert that it is the opposite of 
UndefLower after the initial early exit.

This patch adds a new type StringBlockVal which can be used to emit a
YAML block scalar, which preserves newlines in a multiline string. It
also updates  MappingTraits<DiagnosticInfoOptimizationBase::Argument> to
use it for argument values with more than a single newline.

This is helpful for remarks that want to display more in-depth
information in a more structured way.

Simplify to the generic ISD::ADD/SUB if we don't make use of the result flag.

This mainly helps with ADDCARRY/SUBBORROW intrinsics which get expanded to X86ISD::ADD/SUB but could be simplified further.

This isn't the final fix for our reduction/horizontal codegen, but it takes care 
of a lot of the problems. After we narrow the shuffle, existing combines for 
insert/extract and binops kick in, and we end up with cheaper 128-bit ops.

The avg and mul reduction tests show an existing shuffle lowering hole for 
AVX2/AVX512. I think in its most minimal form this is:

...but we might need multiple fixes to get it right.

This target-independent code won't trigger for cases such as RV32FD where
custom SelectionDAG nodes are generated. These new tests demonstrate such
cases. Additionally, float-arith.ll was updated so that fneg.s, fsgnjn.s, and
fabs.s selection patterns are actually exercised.

Show failure to simplify cases with zero op/flags

llvm-svn: 352196

If a stack trace or similar has a list of addresses from an executable
or DSO loaded at a variable address (e.g. due to ASLR), the addresses
will not directly correspond to the addresses stored in the object file.
If a user wishes to use llvm-symbolizer, they have to subtract the load
address from every address. This is somewhat inconvenient, especially as
the output of --print-address will result in the adjusted address being
listed, rather than the address coming from the stack trace, making it
harder to map results between the two.

This change adds a new switch to llvm-symbolizer --adjust-vma which
takes an offset, which is then used to automatically do this
calculation. The printed address remains the input address (allowing for
easy mapping), whilst the specified offset is applied to the addresses
when performing the lookup.

The switch is conceptually similar to llvm-objdump's new switch of the
same name (see D57051), which in turn mirrors a GNU switch. There is no
equivalent switch in addr2line.

This patch extends TableGen language with !cond operator.
Instead of embedding !if inside !if which can get cumbersome,
one can now use !cond.
Below is an example to convert an integer 'x' into a string:

    !cond(!lt(x,0) : "Negative",
          !eq(x,0) : "Zero",
          !eq(x,1) : "One,
          1        : "MoreThanOne")
