This commit removes an unnecessary addend offset from .dtprelword and .dtpreldword directives on LoongArch. The architecture’s thread pointer (TP) register directly points to the beginning of the Thread-Local Storage (TLS) block, eliminating the need for the previous 0x8000 offset. A new test case is introduced to verify this change.
