optabs: Fix expansion of abs and neg for Float16 [PR123869]HEADtrunkmaster

The problem here is we try to use the widening type before
doing the bitwise expansion of neg/and for floating point types.
This moves the code around to try the bitwise expansion first.

Note this mostly matters for NaNs where you widening (promotion)
would cause a NaN to be slightly different when doing the rounding
back.

Bootstrapped and tested on x86_64-linux-gnu.

	PR middle-end/123869

gcc/ChangeLog:

	* optabs.cc (expand_unop): Move the NEG optab
	handling before the widening code.
	Move the ABS bitwise expansion from expand_abs_nojump
	to before the widening code.
	(expand_abs_nojump): Remove the bitwise expansion trial
	since expand_unop is called right above.
