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.
