[Driver] Ensure ToolChain::LibraryPaths is not empty for non-Darwin

[Driver] Ensure ToolChain::LibraryPaths is not empty for non-Darwin
Follow-up to #81037.
ToolChain::LibraryPaths holds the new compiler-rt library directory
(e.g. `/tmp/Debug/lib/clang/19/lib/x86_64-unknown-linux-gnu`). However,
it might be empty when the directory does not exist (due to the `if
(getVFS().exists(P))` change in https://reviews.llvm.org/D158475).
If neither the old/new compiler-rt library directories exists, we would
suggest the undesired old compiler-rt file name:
```
% /tmp/Debug/bin/clang++ a.cc -fsanitize=memory -o a
ld.lld: error: cannot open /tmp/Debug/lib/clang/19/lib/linux/libclang_rt.msan-x86_64.a: No such file or directory
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
```
With this change, we will correctly suggest the new compiler-rt file name.
Fix #87150

[InstrProfiling] Generate runtime hook for ELF platforms
When using -fprofile-list to selectively apply instrumentation only
to certain files or functions, we may end up with a binary that doesn't
have any counters in the case where no files were selected. However,
because on Linux and Fuchsia, we pass -u__llvm_profile_runtime, the
runtime would still be pulled in and incur some non-trivial overhead,
especially in the case when the continuous or runtime counter relocation
mode is being used. A better way would be to pull in the profile runtime
only when needed by declaring the __llvm_profile_runtime symbol in the
translation unit only when needed.
This approach was already used prior to 9a041a75221ca, but we changed it
to always generate the __llvm_profile_runtime due to a TAPI limitation.
Since TAPI is only used on Mach-O platforms, we could use the early
emission of __llvm_profile_runtime there, and on other platforms we
could change back to the earlier approach where the symbol is generated
later only when needed. We can stop passing -u__llvm_profile_runtime to
the linker on Linux and Fuchsia since the generated undefined symbol in
each translation unit that needed it serves the same purpose.

Fix the addition of Clang's profile runtime library to the link step
when specifying --coverage (or related) flags.
The system for doing this was based on the old LLVM-hosted profile_rt
library, and hadn't been updated for Linux to use the new compiler-rt
library. Also, it couldn't possibly work on multiarch or biarch systems
in many cases. The whole thing now works much the same as the sanitizer
libraries that are built and used out of the compiler-rt repo.
Note that other target OSes haven't been updated because I don't know if
they're doing anything special with the installation path of profile_rt.
I suspect however that *all* of these are wrong and would encourage
maintainers of each target to take a hard look at how compiler-rt
runtime libraries are linked on their platforms.
