re PR debug/54499 (GCC produces wrong debugging information, failure while assembling generated .s file)
PR debug/54499
* cgraphunit.c (assemble_thunk): Don't call source_line debug hook
here, instead call insn_locations_{init,finalize} and initialize
prologue_location.
* g++.dg/debug/pr54499.C: New test.
