[clang][NFC] Clean up conditional statement and make pointer type explicit (#239279)

Remove redundant `else if` and replace with `if` in conditional logic.
The first `if` condition will cause an early return and making the next
condition an `else if` is not beneficial here.

Define `Delim` as a `const auto*` pointer to make the variable type
explicit.

msun: fix behaviour of nextafter*() and nexttoward*() for MAX value

For an edge case at an extreme, e.g., nextafter(-DBL_MAX,-INFINITY)
do not return x+x.  Instead, evaluate x+x and assign it to a volatile
to raise an exception, and then fall through to return the correct
result in current rounding mode.

contrib/bc: remove vs sub-directory

Some of the files in the vs sub-directory are checked out with  CRLF
line breaks via .getattributes. This causes issues when checking out
the source tree with other tools that operate on Git repositories like
"got". Remove the vs sub-directory from the contrib tree, since it is
not required on FreeBSD.

[RegAllocFast] Drop kill flags on virtual registers from the fold tests

The machine verifier now rejects them (#239012). The fast register
allocator works out where each value dies on its own, so the output is the
same without them. That makes tied_input_dies_no_kill_flag a copy of
tied_input_dies, so remove it.

[lldb] Honor the arm64 subtype when launching on Darwin (#239423)

LaunchProcessPosixSpawn treated a CPU subtype of 0 as unset and fell
back to posix_spawnattr_setbinpref_np, which only takes a CPU type.
CPU_SUBTYPE_ARM64_ALL is 0, so launching the arm64 slice of a
universal arm64/arm64e binary ran the arm64e slice while LLDB
reported arm64. debugserver had the same check.

With the check gone, the kernel requires an exact subtype match. Map
arm64_32 to CPU_SUBTYPE_ARM64_32_V8 in debugserver instead of 0.

[lldb] Forward real registers in TestScriptedFrameProvider's frame without variables (#239875)

`test_expression_at_frame_without_variables` failed on aarch64 Linux
with "Couldn't allocate space for materialized struct". Its scripted
frame had no register context, so LLDB couldn't allocate memory in the
inferior to run the expression from that frame. On macOS, debugserver
allocates memory without going through the frame, which is why the test
passed there.

This patch makes the frame forward the registers of the real frame it
replaces, so evaluating an expression there works like at a regular
frame. It still keeps the default `get_variables()`, which the test is
about.
