gollvm: sync with LLVM trunk
This patch brings the gollvm source into sync with LLVM trunk
circa revision cbf25fbed5b46ec47e3ce2799ed9095f2f18ea8f.
Includes a fix to llvm-godumpspec related to the handling of
const-qualified unspecified types (e.g. "const void *"), which the
LLVM DWARF utilities handle slightly differently now.
Fixes golang/go#42355.
