Add clang.arc.used to ModuleHasARC so ARC always runs if said call is present in a module.

clang.arc.used is an interesting call for ARC since ObjCARCContract
needs to run to remove said intrinsic to avoid a linker error (since the
call does not exist).

Exclude the X86/complex-fca.ll test at it probably wasn't supposed to work on Windows

[docs] The STL "binary search" has a non-obvious name.

std::lower_bound is the canonical "binary search" in the STL
(std::binary_search generally is not what you want). The name actually
makes a lot of sense (and also has a beautiful symmetry with the
std::upper_bound algorithm). The name is nonetheless non-obvious.

Also, remove mention of "radix search". It's not even clear how that
would work in the context of a sorted vector. AFAIK "radix search" only
makes sense when you have a trie-like data structure.
