Log:
[arm] Eliminate vfp_reg_type

Remove the VFP_REGS field by converting its meanings into flag
attributes.  The new flag attributes build on each other describing
increasing capabilities.  This allows us to do a better job when
inlining functions with differing requiremetns on the fpu environment:
we can now inline A into B if B has at least the same register set
properties as B (previously we required identical register set
properties).

	* arm.h (vfp_reg_type): Delete.
	(TARGET_FPU_REGS): Delete.
	(arm_fpu_desc): Delete regs field.
	(FPU_FL_NONE, FPU_FL_NEON, FPU_FL_FP16, FPU_FL_CRYPTO): Use unsigned
	values.
	(FPU_FL_DBL, FPU_FL_D32): Define.
	(TARGET_VFPD32): Use feature test.
	(TARGET_VFP_SINGLE): Likewise.
	(TARGET_VFP_DOUBLE): Likewise.
	* arm-fpus.def: Update all entries for new feature bits.
	* arm.c (all_fpus): Update initializer macro.
	(arm_can_inline_p): Remove test on fpu regs.
