Nicolas Miller 510fd283fd [NVPTX] Add ex2.approx.f16/f16x2 support
NOTE: this is a follow-up commit with the missing clang-side changes.

This patch adds builtins and intrinsics for the f16 and f16x2 variants of the ex2
instruction.

These two variants were added in PTX7.0, and are supported by sm_75 and above.

Note that this isn't wired with the exp2 llvm intrinsic because the ex2
instruction is only available in its approx variant.

Running ptxas on the assembly generated by the test f16-ex2.ll works as
expected.

//===----------------------------------------------------------------------===//
// 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:
