[I composed this message on Friday, before I left for the weekend, but

This patch cleans up some build warnings that break native bootstrap.

This test checks that the stack pointer is handled correctly in
prologue/epilogue of Cortex-M interrupt handlers. An interrupt handler may
be called when stack is not double-word aligned. The prologue of the
interrupt handler aligns the stack pointer and the epilogue restores the
original stack
This test relies on epilogue generated in RTL to provide register liveness
information that enables peephole optimization.

Hello,
This patch started as an attempt to remove #include output.h from

references are output as top-level asm statements. It's a bit of a
hack, but it works and it's a better hack than writing to
asm_out_file from a front end,
