compiler: Rework LTO settings for some Zig-provided libraries.

* compiler-rt and mingw32 have both run into LLD bugs, and LLVM disables LTO for
  its compiler-rt, so disable LTO for these.
* While we haven't run into any bugs in it, LLVM disables LTO for its libtsan,
  so follow suit just to be safe.
* Allow LTO for libfuzzer as LLVM does.
