Subject: [PATCH] common: Work around GCC8 _xgetbv bug
clang and earlier GCC versions do not provide the _xgetbv intrinsic.
GCC8 does, but unfortunately it's broken.
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85684).
Re-use our _xgetbv implementation to avoid the bug, but rename it to
avoid compilation errors as well.
