[llvm] Remove unneeded global inits (PR #129299)

[JP Hafer via llvm-commits]

https://github.com/jph-13 created https://github.com/llvm/llvm-project/pull/129299

Theses consts in ASMTargetParser were causing unnecessary global initialization fuctions.
_GLOBAL__sub_I_ARMTargetParser.cpp
_GLOBAL__sub_I_Triple.cpp

Both functions init the same consts. I messed up the first PR on this sorry.
