Srinath Parvathaneni 5291fe3cd1 aarch64: Add support for bfloat16 in gdb. 
This patch adds support for bfloat16 in AArch64 gdb.
Also adds the field "bf" to vector registers h0-h31.
Also adds the vector "bf" to h field in vector registers v0-v31.

The following is how the vector register h and v looks like.

Before this patch:
(gdb) p $h0
$1 = {f = 0, u = 0, s = 0}
(gdb) p/x $h0
$2 = {f = 0x0, u = 0x0, s = 0x0}
(gdb) p $v0.h
$3 = {f = {0, 0, 0, 0, 0, 0, 0, 0}, u = {0, 0, 0, 0, 0, 0, 0, 0}, s = {0, 0, 0, 0, 0, 0, 0, 0}}
(gdb) p/x $v0.h
$4 = {f = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, u = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0},
      s = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}

After this patch:
(gdb) p $h0
$1 = {bf = 0, f = 0, u = 0, s = 0}
(gdb) p/x $h0
$2 = {bf = 0x0, f = 0x0, u = 0x0, s = 0x0}
(gdb) p $v0.h
$3 = {bf = {0, 0, 0, 0, 0, 0, 0, 0}, f = {0, 0, 0, 0, 0, 0, 0, 0}, u = {0, 0, 0, 0, 0, 0, 0, 0},
      s = {0, 0, 0, 0, 0, 0, 0, 0}}
(gdb) p/x $v0.h
$4 = {bf = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, f = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0},
      u = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, s = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}
