Fix PR target/70496

While doing the unified asm rewrite - I inadvertently changed the
meaning of ASM_APP_OFF which causes failures when folks who know what
they are doing switch between arm and thumb states within a
function. The intent of the unified asm rewrite was not to affect any
inline assembler code in that it would remain in divided syntax by
default and switching back to unified asm in normal compiled code
after the inline assembler block. Thanks to Jim Wilson for pointing it
out on the linaro list.

Fixed thusly and a test is added. Tested arm-none-eabi cross and
applied.
