Summary: This is updating the OpenMP status table. Cray has volunteered for `defaultmap` and supporting `in_reduction` on the `target` construct, so the status on those entries from was changed from "unclaimed". Also, a new entry was added for supporting non-contiguous arrays sections on the `target update` directive.

Assume that the user knows what they're doing if they provide a char
literal as an array index. This more closely matches the behavior of
GCC.

GWP-ASan didn't include SANITIZER_COMMON_CFLAGS, and thus would produce
LLVM bitcode files, when compiler-rt is generally built without LTO.
This allows crtbegin and crtend to be built, allowing RISC-V
to no longer rely on implementations from libgcc.

Add options to control floating point behavior: trapping and
exception behavior, rounding, and control of optimizations that affect
floating point calculations. More details in UsersManual.rst.

If a GCC installed is not detected, the driver would default to
the root of the filesystem. This is not ideal when this doesn't
match the install directory of the toolchain and can cause
undesireable behavior such as picking up system libraries or
the system linker when cross-compiling.

Atomic compound expressions try to use atomicrmw if possible, but this
path doesn't set the Result variable, leaving it to crash in later code
if anything ever tries to use the result of the expression. This fixes
that issue by recalculating the new value based on the old one
atomically loaded.
Add the remaining math and common builtin functions from the OpenCL C
specification.

We have a vector compare reduction problem seen in PR39665 comment 2:
https://bugs.llvm.org/show_bug.cgi?id=39665#c2
Or slightly reduced here:
define i1 @cmp2(<2 x double> %a0) {
%a = fcmp ogt <2 x double> %a0, <double 1.0, double 1.0>
%b = extractelement <2 x i1> %a, i32 0
%c = extractelement <2 x i1> %a, i32 1
%d = and i1 %b, %c
ret i1 %d
}
SLP would not attempt to turn this into a vector reduction because there is an
artificial lower limit on that transform. We can not completely remove that limit
without inducing regressions though, so this patch just hacks an extra attempt at
creating a 2-way reduction to the end of the analysis.
As shown in the test file, we are still not getting some of the motivating cases,
so follow-on patches will be needed to solve those cases.

`saa` and `saad` are 32-bit and 64-bit store atomic add instructions.
memory[base] = memory[base] + rt
These instructions are available for "Octeon+" CPU. The patch adds support
for both instructions to MIPS assembler and diassembler and introduces new
CPU type - "octeon+".
Next patches will implement `.set arch=octeon+` directive and `AFL_EXT_OCTEONP`
ISA extension flag support.

Following up on https://reviews.llvm.org/D62221, this change introduces
the settings plugin.process.gdb-remote.use-g-packet-for-reading. When
they are on, 'g' packets are used for reading registers.
Using 'g' packets can improve performance by reducing the number of
packets exchanged between client and server when a large number of
registers needs to be fetched.

Summary:
When adjusting function entry counts after inlining, Funciton::setEntryCount is called without providing an import function list. The side effect of that is the previously set import function list will be dropped. The import function list is used by ThinLTO to help import hot cross module callee for LTO inlining, so dropping that during ThinLTO pre-link may adversely affect LTO inlining. The fix is to keep the list while updating entry counts for inlining.
