[release-branch.go1.2] cmd/5l, runtime: fix divide for profiling tracebacks on ARM

««« CL 19910044 / 9eb64f5ef3a6
cmd/5l, runtime: fix divide for profiling tracebacks on ARM

Two bugs:
1. The first iteration of the traceback always uses LR when provided,
which it is (only) during a profiling signal, but in fact LR is correct
only if the stack frame has not been allocated yet. Otherwise an
intervening call may have changed LR, and the saved copy in the stack
frame should be used. Fix in traceback_arm.c.

2. The division runtime call adds 8 bytes to the stack. In order to
keep the traceback routines happy, it must copy the saved LR into
the new 0(SP). Change

        SUB $8, SP

into

        MOVW    0(SP), R11 // r11 is temporary, for use by linker
        MOVW.W  R11, -8(SP)

to update SP and 0(SP) atomically, so that the traceback always
sees a saved LR at 0(SP).

Fixes #6681.

[release-branch.go1.2] cmd/cgo: accept extra leading _ on __cgodebug_data for all object formats

««« CL 19780043 / 8b49cdda6ff4
cmd/cgo: accept extra leading _ on __cgodebug_data for all object formats

The current Windows build breakage appears to be because
the Windows code should be looking for __cgodebug_data
not ___cgodebug_data. Dodge the question everywhere by
accepting both.
