The experimental-library-flag.cpp test was failing on FreeBSD builders,
which turned to be caused by missing support for -stdlib=libcstdc++ (and
just using a hardcoded libc++ in all cases).
Simplify FreeBSD::AddCXXStdlibLibArgs() by deferring to the parent class
and dealing with the FreeSBD < 14 profiling support as a special case.
While touching the test file also drop the unnecessary `-o %t.o`. This is
not needed since the RUN lines use -### and don't produce any output.

While looking at other usage of getOSMajorVersion() I noticed if a version number is not
included in the FreeBSD triple it won't include the --hash-style=both linker option or
not disable the use of .init_array. Without a version should be the latest.
FreeBSD 8 and 9 are no longer supported. So simplify things with the version handling
as well.

This matches OpenBSD, and it supports Swift's use of clang for its C interop
functionality. Recent changes to Swift use AddClangSystemIncludeArgs() to
inspect the cc1 args; this doesn't work for platforms where cc1 adds standard
include paths implicitly. See:
<cf3354222d>
Also clean up InitHeaderSearch, making it clearer which targets manage header
search paths in the driver.

Prior to FreeBSD 14, FreeBSD provided special _p.a libraries for use
with -pg. They are no longer used or provided. If the target does
not specify a major version (e.g. amd64-unknown-freebsd, rather than
amd64-unknown-freebsd12) default to the new behaviour.

All supported FreeBSD releases use libc++, so default to it if the
target's major version is not specified.

The test specified amd64-unknown-freebsd40.0 rather than 14.0. Since
40 is greater than 14 the test (for behaviour new in FreeBSD 14) worked
despite the typo.

In FreeBSD 14 the project will deprecate the _p special profiling
libraries.
Support for -pg (i.e., mcount) still exists but libraries compiled
with -pg will not be built by default, so stop linking against them.

Also introduce -stdlib=platform to override the configured value
and use it to make the tests always pass.

C++ programs compiled for profiling (using `-pg`) should be linked with
`-lc++_p` (or `-lstdc++_p`, depending on the `-stdlib=` setting), not
with the regular C++ libraries.
Add a `FreeBSD::AddCXXStdlibLibArgs()` override to handle this, and add
a test case for it. While here, extend the test case for the proper
passing of -lm and -lm_p.
