The dynamically linked ASan tests rely on `LD_LIBRARY_PATH` to find
`libclang_rt.asan-*.so` at runtime.
However, the Solaris runtime linker `ld.so.1` also supports more specific
variables: `LD_LIBRARY_PATH_32` and `LD_LIBRARY_PATH_64` respectively. If
those happen to be set, `LD_LIBRARY_PATH` is ignored. In such a case, all
dynamically linked ASan tests `FAIL`. For i386 alone, this affects about
200 tests.
The following patch fixes that by also setting `LD_LIBRARY_PATH_{32,64}` on
Solaris.
Tested on `amd64-pc-solaris2.11` both with only `LD_LIBRARY_PATH` set and
with `LD_LIBRARY_PATH_{32,64}` set too.
