Simon Pilgrim 2853ae3c1b [X86] Update SSE/AVX ABS intrinsics to emit llvm.abs.* (PR46851)
We're now getting close to having the necessary analysis/combines etc. for the new generic llvm.abs.* intrinsics.

This patch updates the SSE/AVX ABS vector intrinsics to emit the generic equivalents instead of the icmp+sub+select code pattern.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:

If you find a bug in Clang, please file it in the LLVM bug tracker:
