[PATCH, ARM] PR58361 fix failure to conditionalize VFP instruction

[Richard Earnshaw <rearnsha at arm dot com>]

PR target/58361 is a wrong code bug where we treat an instruction as
conditional but fail to put the conditional marker on the assembly.
Since the instruction can be correctly executed as a conditional
instruction, the fix is to enable that and to put out the condition code
accordingly.

The particular testcase doesn't trigger on 4.8 or trunk, but the bug is
still there so fixed on all three branches.  A slight variant of the
patch is needed for the release branches due to the changes that have
happened on trunk since the last release was made.  Both versions of the
patch are attached.

	PR target/58361
	* arm/vfp.md (combine_vcvt_f32_<FCVTI32typename>): Fix pattern to
	support conditional execution.
	(combine_vcvt_f64_<FCVTI32typename>): Likewise.

R.
