llvm/test/CodeGen/AArch64/elf-globals-pic.ll: Since https://reviews.llvm.org/D91734, elf-globals-static.ll test contains several `CHECK-PIC` lines. They do not seem to bring any value since there are no FileCheck run lines checking against this prefix. The right place for such tests should be elf-globals-pic.ll, which already contains check lines being deleted in this commit. Both elf-globals-pic.ll and elf-globals-static.ll were created after splitting arm64-elf-globals.ll in6dbd0ea, and having `CHECK-PIC` lines in elf-globals-static.ll seems like an issue occurred because of git thinking that elf-globals-pic.ll is a new file and elf-global-static.ll is a rename of arm64-elf-globals.ll. llvm/test/CodeGen/AArch64/tagged-globals-pic.ll: Similar to elf-globals-pic.ll, contains unneeded `CHECK-SELECTIONDAGISEL` and `CHECK-GLOBALISEL` directives not checked by any FileCheck invocation. These directives are present in tagged-globals-static.ll. Both tests are present in the code tree sincefd32639when tagged-globals.ll was splitted into tagged-globals-{pic|static}.ll.
