Herald added a project: LLVM.

The LLVM test suite has its own way of detecting the system
architecture. This adds support in that file for detecting RISC-V.

We use "riscv64" to identify 64-bit RISC-V, and "riscv32" to identify 32-bit
RISC-V, so that attempting to detect "riscv" matches any version of RISC-V.
