reproduce files from manually crashing compiler with SIGBUS.
FreeBSD clang 9.0.1 could compile this code OK, but FreeBSD clang 10.0.0
llvmorg-10.0.0-rc3-1-gc290cb61fdc gets stuck in an infinite loop, and so does
current llvm master.
Code is from FreeBSD security/nss package building on powerpc64.</pre>
