Subject: [PATCH] [test][AArch64][CodeGen] Delete redundant check lines

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 in
6dbd0eac02bf98a7585904ad69d0d9950947c9b4, 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 since fd32639823e4d74eadbca5b0a9610a87d69b25c8
when tagged-globals.ll was splitted into tagged-globals-{pic|static}.ll.
