Ignore vendor name in Clang version number.

For example, FreeBSD prepends "FreeBSD" to version string, e.g.,

FreeBSD clang version 11.0.0 (git@github.com:llvm/llvm-project.git llvmorg-11.0.0-rc2-0-g414f32a9e86)
Target: x86_64-unknown-freebsd13.0
Thread model: posix
InstalledDir: /usr/bin

This prevented us from properly detecting AVX support, etc.
