This is necessary because LLVM defines many options in global variables
that are modified when invoking Clang. In particular, LLVM 10 seems to
have a bug in which it always sets the -pgo-warn-misexpect flag. Setting
it multiple times (over various cc1 invocations) results in an error:
clang (LLVM option parsing): for the --pgo-warn-misexpect option: may only occur zero or one times!
This is fixed by running the Clang invocation in a new `tinygo`
invocation.
Because we've had issues with lld in the past, also run lld in a
separate process so similar issues won't happen with lld in the future.
