Hello!
Insn predicates have to allow all constraints during LRA, not only
after reload_completed is true.

PR target/72843
* config/i386/i386.md (*movtf_internal): Use
lra_in_progress || reload_completed instead of !can_create_pseudo_p
in the insn constraint.
(*movxf_internal): Ditto.
(*movdf_internal): Ditto.
(*movsf_internal): Ditto.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32} and
committed to mainline.
The patch will be backported to to other release branches after a week.
Uros.
