llvm-mc --assemble prints an initial `.text` from `initSections`. This is weird for quick assembly tasks that do not specify `.text`. Omit the .text by moving section directive printing from `changeSection` to `switchSection`. switchSectionNoPrint now correctly calls the `changeSection` hook (needed by MachO). The initial directives of clang -S are now reordered. On ELF targets, we get `.file "a.c"; .text` instead of `.text; .file "a.c"`. If there is no function, `.text` will be omitted.
