build: use LLVM from an install directory

Require the LLVM to be installed into deps/llvm/install, and use the
LLVM from there. This simplifies the include and library paths. It also
resembles more the way things should work if the LLVM was provided by
the distribution.

We still need some hacks to include the private clang CodeGen headers,
though.

build: remove setting libdirs in premake4.lua

"libdirs { libdir }" in the main premake4.lua file causes Debug_x32
directory to be added for the libdirs for all builds. I think that's a
bug in premake, as at the same place setting, say, "targetdir" works
fine.

However, setting "libdir" to "libdirs" is not needed at all, so let's remove it.
