Subject: [C++11] Remove LLVM_HAS_CXX11_TYPETRAITS now that it is a constant due
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=f07a95af8c2f54679f4a00a67caa0f94c2e79088

[C++11] Remove LLVM_HAS_CXX11_TYPETRAITS now that it is a constant due
to the build being C++11.

There is clearly still plenty of simplification than can be done here by
using standard type traits instead of rolling our own in many places.
