github: Run all the compiler-rt tests, on both i686 and x86_64

These tests should now all pass on both architectures; the
check-asan tests for the static CRT are skipped automatically,
the failures in check-interception have been fixed by compiling
the tests with the --large-address-aware flag, and the
check-asan-dynamic tests on i686 have been fixed - all by
Alvin Wong.
