test: add explicit targets for some tests These tests currently expect MachO section names and do not provide a target. Explicitly provide one. llvm-svn: 271212

// REQUIRES: arm-registered-target,x86-registered-target
CodeGen: tweak CFConstantStrings for COFF and ELF Adjust the constant CFString emission to emit into more appropriate sections on ELF and COFF targets. It would previously try to use MachO section names irrespective of the file format. llvm-svn: 271211

CodeGen: try harder to make the CFString structure RW The previous change was insufficient to mark the content as read-write as the structure itself was marked constant. Adjust this and add tests to ensure that the section is marked appropriately as being read-write. llvm-svn: 277200
