[clang] Don't spuriously pass -stdlib=libc++ to CC1 on Darwin
Previously, we would be passing down -stdlib=libc++ from the Driver
to CC1 whenever the default standard library on the platform was libc++,
even if -stdlib= had not been passed to the Driver. This meant that we
would pass -stdlib=libc++ in nonsensical circumstances, such as when
compiling C code.
This logic had been added in
b534ce46bd40 to make sure that header
search paths were set up properly. However, since libc++ is now the
default Standard Library on Darwin, passing this explicitly is not
required anymore. Indeed, if no -stdlib= is specified, CC1 will end
up using libc++ if it queries which standard library to use, without
having to be told.
Not passing -stdlib= at all to CC1 on Darwin should become possible
once CC1 stops relying on it to set up framework search paths.
Furthermore, this commit also removes a diagnostic checking whether the
deployment target is too old to support libc++. Nowadays, all supported
deployment targets use libc++ and compiling with libstdc++ is not
supported anymore. The Driver was the wrong place to issue this
diagnostic since it doesn't know whether libc++ will actually be linked
against (e.g. C vs C++), which would lead to spurious diagnostics.
Given that these targets are not supported anymore, we simply drop
the diagnostic instead of trying to refactor it into CC1.

runtime functions. This is in keeping with some other compilers which also
return some results when `N1` and/or `N2` are negative.
The special case for `x == 0` is handled in different runtime functions
for each of `BESSEL_JN` and `BESSEL_YN`. The lowering code checks for this
case and inserts the checks and the appropriate runtime calls in FIR.
The existing tests for the two intrinsics was modified to keep the style
consistent with the additional lowering tests that were added.

[LoopPeel] Expose ValueMap of last peeled iteration. NFC
The value map of last peeled iteration is computed within peelLoop API.
This patch exposes it for callers of peelLoop.
While this is not currently used by upstream passes, we have a usecase
downstream which benefits from this API update. Future users of peelLoop
can also use the ValueMap if needed.
Similar value maps are exposed by other loop utilities such as loop
cloning.

[lit] Script to automate use of %(line-n). Use in CodeComplete tests.
Tests where the RUN-lines/CHECK-ed output refer to line numbers in the test
file are a maintenance burden, as inserting text in the appropriate place
invalidates all the subsequent line numbers.
Lit supports %(line+n) for this, and FileCheck supports [[@LINE+N]].
But many existing tests don't make use of it and still need to be modified.
This commit adds a script that can find line numbers in tests according to a
regex and replace them with the appropriate relative-line reference.
It contains some options to avoid inappropriately rewriting tests where absolute
numbers are appropriate: a "nearby" threshold and a refusal by default to
replace only some matched line numbers.
I've applied it to CodeComplete tests, this proves the concept but also are the
single worst group of tests I've seen in this respect.
These changes are likely to hit merge conflicts, but can be regenerated with:
```
find ../clang/test/CodeCompletion/ -type f | grep -v /Inputs/ | xargs ../llvm/utils/relative_lines.py --verbose --near=20 --pattern='-code-completion-at[ =]%s:(\\d+):' --pattern='requires fix-it: {(\d+):\d+-(\d+):\d+}'
