Subject: [PATCH] Documentation/llvm: Update Supported Arch table

While watching Michael's new talk on Clang-built-Linux, I noticed the
arch table in our docs that he refers to is outdated.

Add hexagon and User Mode. Bump MIPS and RISCV to LLVM=1. PowerPC is
almost LLVM=1 capable; ppc64le works, but ppc64 (big endian) and ppc32
still need more work.
