This will cut out the few seconds it takes to run make install.
Seems to prevent the warning about linking bitcode with different triples.

* Add tests to associated types * Fix type mistmatch of types with projection Structures with members that had type projections in their declaration were being handled incorrectly. We were only normalizing the types when the projection was visited, which could impact on how we identify whether this structure already existed or not. This change normalizes all types before starting to codegen the entire type. Co-authored-by: Daniel Schwartz-Narbonne <[email protected]>

This series turns LLVM into a git submodule of Rust and changes the build system to completely manage the LLVM build.
The submodule lives in src/llvm and its remote is git://github.com/brson/llvm.git. Note that this is our fork of LLVM, which pcwalton will be using to do some work on stack growth. Hopefully it will be short-lived and we will switch back to the official git repo soon.
The configure script handles the calls to 'git submodule init' and 'git submodule update' and automatically reconfigures when the submodule needs to update. configure sets up LLVM build directories for every target specified, so when we cross-compile to x86_64 it will be building two LLVMs (eventually we will not want to build LLVMs for every target because we might not want - or be able - to build rustc for every target).
If you want to provide your own LLVM you can still configure with --llvm-root. We will still keep the submodule up to date, but not do the LLVM build.
I am going to try to configure the bots to not clobber the LLVM build on every checkout.
