We'd like to make various instrprof globals large to make them not contribute to relocation pressure since there are no direct accesses to them in the module. Similar to what was done for asan_globals in #74514. This affects the __llvm_prf_vals, __llvm_prf_vnds, and __llvm_prf_names sections. The reland fixes platform.ll.
