Jeremy Volkman cc8f113489 Use artifact_name_pattern to specify proper macos and windows artifact names.
On macos, dynamic libraries are generated as "libfoo.dylib".

On windows, executables end with ".exe", static libraries end with ".lib",
and dynamic libraries end with ".dll".

Jeremy Volkman 0db5d2d9e6 Adds supports_dynamic_linker feature
With this feature, cc_library generates a .so as well as a .a and the

Motiejus Jakštys 527ebbc863 fastbuild: replace -gmlt with -O0
- -gmlt is a noop in zig, because -g is a default anyway.
- -O0 was fixed in ziglang/zig 02ba3cb25cc8ee2637c6fb7bcb935722490ba05c

Motiejus Jakštys 4cfc30dd1c [fastbuild] use -fno-lto
This is very cache-unfriendly, because quite a lot of work is done
during the final linking stage. Let's see how this improves performance
of fastbuild.

laurynasl b73d167c6c Support bazel compilation_mode
Bazel has a special command line option (--compilation_mode) for specifying how
c artifacts should be compiled. Copy over the implementation without too much
thought on whether they make sense.

See https://docs.bazel.build/versions/main/user-manual.html#flag--compilation_mode.

!!! Due to a regression in zig-cc, debug symbols are available under --compilation_mode opt

```
laurynasl@laurynasl ~/bazel-zig-cc
 % bazel build -c opt //test/c:which_libc 2>/dev/null && bazel-bin/test/c/which_libc && gdb -batch --ex 'info line main' bazel-bin/test/c/which_libc
