Fix https://llvm.org/PR49498.
The check notices 2 sides of a conditional operator have types with a different constness and so tries to examine the implicit cast.
As one side is infinity, the float narrowing detection sees when its casted to a double(which it already was) it thinks the result is out of range.
I've fixed this by just disregarding expressions where the builtin type(without quals) match as no conversion would take place.
However this has opened a can of worms. Currenty `float a = std::numeric_limits<double>::infinity();` is marked as narrowing.
Whats more suspicious is `double a = std::numeric_limits<float>::infinity();` is also marked as narrowing.
It could be argued `double inf -> float inf` is narrowing, but `float inf -> double inf` definitely isnt.

[Clang] Fix defaulted equality operator so that it does not attempt to compare unnamed bit-fields
If we look at class.bit p2 it tells us that that unnamed bit-fields are not
members and class.compare.default p5 tells us that we should only compare
non-static data members of the class.

test-release.sh: build projects and runtimes lists with semicolons
While doing a test-release.sh run on FreeBSD, I ran into a sed error due
to the introduction of the GNU extension '\s' in commit
500587e23dfd.
Scanning for blanks (spaces and tabs) could be done in a more portable
fashion using the [[:blank:]] character class. But it is easier to avoid
the original problem, which is that the projects and runtime lists have
to be separated by semicolons, and cannot start with a semicolon.
Instead, use the shell's alternate value parameter expansion mechanism,
which makes it easy to append items to lists with separators in between,
and without any leading separator. This also avoids having to run sed on
the end result.
In addition, build any selected runtimes in the second phase, otherwise
the third phase can fail to find several symbols in compiler-rt, if that
has been built. This is because the host's compiler-rt is not guaranteed
to have those symbols.

Fix tls_get_addr handling for glibc >=2.25
This changes the sanitizers' tls_get_addr handling from
a heuristic check of __signal_safe_memalign allocations
(which has only been used in a since deprecated version
of Google's runtime), to using the sanitizers' interface
function to check if it is a malloc allocation (used
since glibc >= 2.25).
This is one of the approaches proposed by Keno in
https://github.com/google/sanitizers/issues/1409#issuecomment-
1214244142
This moves the weak annotation of __sanitizer_get_allocated_size/begin from the header to sanitizer_tls_get_addr.cpp, as suggested by Vitaly in D148060.
