Summary:
After the overhaul of the GPU build the documentation pages were a
little stale. This updates them with more in-depth information on
building the GPU runtimes and using them. Specifically using them goes
through the differences between the offloading and direct compilation
modes.
Summary:
This directory is leftover from when we handled both AMDGPU and NVPTX in
the same build and merged them into a pseudo triple. Now the only thing
it contains is the RPC server header. This gets rid of it, but now that
it's in the base install directory we should make it clear that it's an
LLVM libc header.
This patch does the noisy work of removing the test opcodes from the
exported interface to an interface that is only visible in `libc`. The
benefit of this is that we both test the exported RPC registration more
directly, and we do not need to give this interface to users.
I have decided to export any opcode that is not a "core" libc feature as
having its MSB set in the opcode. We can think of these as non-libc
"extensions".

This patch updates some of the documentation for the GPU libc project.
There is a lot of work still to be done, but this sets the general
outline.
