arm.h (enum floating_point_type): Delete. 

* arm.h (enum floating_point_type): Delete.  Replace with...
(enum fputype): ... new.
(FPUTYPE_DEFAULT): Renamed from FP_DEFAULT.  Values reworked.
* linux-elf.h (FPUTYPE_DEFAULT): Likewise.
* arm.md (attr fpu): Reworked for new underlying enum values.
* arm.c	(arm_fpu_arch): Now enum fputype.
(arm_fpu_tune): Renamed from arm_fpu.  Now enum fputype.
(arm_override_options, arm_output_epilogue, arm_expand_prologue):
Update uses of arm_fpu_arch and arm_fpu_tune.
