[ARM] PR target/70830: Avoid POP-{reglist}^ when returning from interrupt handlers
PR target/70830
* config/arm/arm.c (arm_output_multireg_pop): Avoid POP instruction
when popping the PC and within an interrupt handler routine.
Add missing tab to output of "ldmfd".
(output_return_instruction): Output LDMFD with SP update rather
than POP when returning from interrupt handler.
* gcc.target/arm/interrupt-1.c: Change dg-compile to dg-assemble.
Add -save-temps to dg-options.
Scan for ldmfd rather than pop instruction.
* gcc.target/arm/interrupt-2.c: Likewise.
* gcc.target/arm/pr70830.c: New test.
