[PATCH] D22639: Add flag to PassManagerBuilder to disable GVN Hoist Pass.

[Alina Sbirlea via llvm-commits]

To clarify, the tests in question are not upstreamed to the LLVM test suite, so there's nothing to disable here.
There is currently a work-around in Halide that is fairly ugly IMO (https://github.com/halide/Halide/blob/master/src/CodeGen_LLVM.cpp#L971). 
Halide explicitly creates and invokes the PassManagerBuilder, so that's where having the disable option would be useful.
