D_LP64 is already predefined by d/d-builtins.cc if POINTER_SIZE == 64,
and it should not be confused with any LP64 ABI model. I haven't
checked what happens if you predefine the same version twice.

D_LP32 is not a standardized predefined version condition as far as I'm
aware. Maybe these should be LoongArch_LP64 and LoongArch_LP32 instead.

These tests would be added anyway as part of merging the upstream DMD
mainline, but otherwise I wouldn't object to update them here.
