Previously, pa_asm_output_mi_thunk() internally output the assembler
directives needed
for thunks. This patch switches to using final_start_function() an
final_end_function() to
generate these directives. This has the advantage that these
functions also ouput debug
info as well. This fixes PR debug/55794.
Tested on hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11 and hppa-unknown-
linux-gnu.
Committed to trunk.

* config/pa/pa.c (pa_output_function_epilogue): Skip address and code
size accounting for thunks.
(pa_asm_output_mi_thunk): Use final_start_function() and
final_end_function() to output function start and end directives.
