Support printing of 16 byte real/complex type for Flang compiler

Browse Source 
Currently GDB is not able to print correct value for real/complex type
from binary generated from Flang compiler. This is due to GDB not able
to recognise and determine correct format floatformats_ia64_quad and
instead falling back to default_floatformat_for_type. This leads
incorrect output.
Now function i386_floatformat_for_type is fixed to correctly identify
Flang generated 16 byte real/complex type.

	* gdb/i386-tdep.c (i386_floatformat_for_type): Added conditions
	to match 16 byte real/complex type generated by Flang compiler.
