  -----------
  [WebAssembly] Add SIMD integer min/max builtins

Summary:
Although SIMD integer min/max operations can be expressed using the ?:
operator in C++, that operator is disallowed for vectors in C. As a
workaround, this change introduces new WebAssembly-specific builtin
functions that lower to the desired vector icmp/select sequences.
