Thomas Lively 1e9c39a3f9 [WebAssembly] Use functions instead of macros for const SIMD intrinsics
To improve hygiene, consistency, and usability, it would be good to replace all
the macro intrinsics in wasm_simd128.h with functions. The reason for using
macros in the first place was to enforce the use of constants for some arguments
using `_Static_assert` with `__builtin_constant_p`. This commit switches to
using functions and uses the `__diagnose_if__` attribute rather than
`_Static_assert` to enforce constantness.

The remaining macro intrinsics cannot be made into functions until the builtin
functions they are implemented with can be replaced with normal code patterns
because the builtin functions themselves require that their arguments are
constants.

This commit also fixes a bug with the const_splat intrinsics in which the f32x4
and f64x2 variants were incorrectly producing integer vectors.

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