i386: Fix *vec_extractv2sf_1 and *vec_extractv2sf_1 shufps alternative [PR93828]
shufps moves two of the four packed single-precision floating-point values
from *destination* operand (first operand) into the low quadword of the
destination operand. Match source operand to the destination.
PR target/93828
* config/i386/mmx.md (*vec_extractv2sf_1): Match source operand
to destination operand for shufps alternative.
(*vec_extractv2si_1): Ditto.
testsuite/ChangeLog:
PR target/93828
* g++.target/i386/pr93828.C: New test.
