[GAS][ARM][3/3]Add armv8.2 fp16 scalar instruction support. [Based on SE_H instruction shape for .f16, u16, s16, .16 type specifier]

[Renlin Li]

Hi Nick,

Thank you for pointing this out!

No, the test case doesn't work on PE and COFF targets.

First of all, the objdumped assembly depends on the mapping symbols to 
correctly
print data and instruction.

for example, for elf target:

0000000c <label>:
    c:    00000ffe     .word    0x00000ffe

for wince target:

0000000c <label>:
    c:    00000ffe     strdeq    r0, [r0], -lr

There are other minor differences as well.
I will update the test case.

Thanks!
Renlin
