Documentation/llvm: Update Supported Arch table

[PATCH] Documentation/llvm: Update Supported Arch table

Posted by Nick Desaulniers 3 years, 10 months ago

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arch table in our docs that he refers to is outdated.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.
