  1. [WebAssembly] Implement prototype f32.load_f16 instruction. 

    Adds a builtin and intrinsic for the f32.load_f16 instruction.

The instruction loads an f16 value from memory and puts it in an f32.
Specified at:
https://github.com/WebAssembly/half-precision/blob/29a9b9462c9285d4ccc1a5dc39214ddfd1892658/proposals/half-precision/Overview.md

Note: the current spec has f32.load_f16 as opcode 0xFD0120, but this is incorrect
and will be changed to 0xFC30 soon.

  2. Use short for builtin. Alternatively we could use _Float16, but then 

    need to enable that for the platform.
