[PR87874] avoid const-wide-int subreg in LRA
Just like CONST_INT, CONST_WIDE_INT is VOIDmode, so LRA might be
tempted to build a SUBREG to "convert" it to the wanted mode. That's
no use. Test for CONST_SCALAR_INT_P instead of CONST_INT_P so that we
skip the subreg creation for both.

* lra.c (lra_substitute_pseudo): Do not create a subreg for
const wide ints.
