Weining Lu c4eb880d43 Revert "[LoongArch] Change 'using namespace llvm;' to 'namespace llvm {' in LoongArchTargetParser.cpp. NFC"
This reverts commit 586321467a0d48573ae643e837a6c4eaf6bc75db.

Reason to revert:
These changes are inconsistent with the [[https://llvm.org/docs/CodingStandards.html#use-namespace-qualifiers-to-implement-previously-declared-functions|LLVM stype guide]].
