Update LLVM version: 3.5 => 3.6

We branched 3.5, it's now time to work on 3.6.

This is Sylvestre's patch from [1] plus regenerated configure
file by me, and minus the release notes reset, which Sean
pointed out [2] should happen later.

[Debug Info] add DISubroutineType and its creation takes DITypeArray. 

DITypeArray is an array of DITypeRef, at its creation, we will create
DITypeRef (i.e use the identifier if the type node has an identifier).

This is the last patch to unique the type array of a subroutine type.
