Bill Wendling 33bd6a2d6c Add .pushsection', .popsection', and `.previous' directives to Darwin ASM.
There are situations where inline ASM may want to change the section -- for
instance, to create a variable in the .data section. However, it cannot do this
without (potentially) restoring to the wrong section. E.g.:

  asm volatile (".section __DATA, __data\n\t"
                ".globl _fnord\n\t"
                "_fnord: .quad 1f\n\t"
                ".text\n\t"
                "1:" :::);

This may be wrong if this is inlined into a function that has a "section"
attribute. The user should use `.pushsection' and `.popsection' here instead.

The addition of `.previous' is added for completeness.
