Partially revert "LoongArch: Fix bug123807."

Browse Source 
This reverts the loongarch.cc change of the commit
4df77a2542.

PR 123807 turns out to be a special case of the middle-end PR 124250.
The previous ad-hoc fix is unneeded now since the underlying middle-end
issue is fixed, so revert it but keep the test case.
