A patch has been added to inject environment variables into the CMake
test runner, the `INCLUDE_PATH` variable has been specified, and the
merged LLVM derivation has been updated to refer to the split outputs.
Contains the combined single-commit work by both @jnetod and myself
from NixOS/nixpkgs#122665. Brings the build up to LLVM 10, switches to
`symlinkJoin` for putting Clang where the CMake build expects it, and
updates to a fresh update of Terra that works around a few LLVM bugs.
Terra heavily depends on its ability to interface with C APIs, but
without scanning NIX_CFLAGS_COMPILE, it's awkward and annoying to set up
imports correctly (by scanning and adding the flags yourself) in every
single project.
Luckily most of the Clang initialization is hidden away, but the Lua
code for the Terra library handles all the high-level stuff, so we patch
it in there.
This allows simple examples like:
C = terralib.includec("zlib.h")
to work instantly, provided `zlib` is a Nix dependency.

* llvmPackages_35 -> llvmPackages_38
* static llvm no longer needed
* multiple outputs, this generates the following results:
- out/lib/terra.so
- bin/bin/terra
- dev/include/terra/*.h
- static/lib/libterra.a
