  Log Message:
  -----------
  The _Float16 type is supported on x86 systems with SSE2 enabled.
Operations are emulated by software emulation and “float” instructions.
This patch is allowing the support of _Float16 type without the use of
-max512fp16 flag. The final goal being, perform _Float16 emulation for
all arithmetic expressions.
