All of the jit testcases that generate debuginfo appear to have been failing since r240228 on their 2nd in-process iteration on this assertion in set_early_dwarf's ctor:
gcc_assert (! early_dwarf_finished); Root cause is that the global is never reset at the end of compilation, which this patch fixes in the obvious way. Successfully bootstrapped®rtested on x86_64-pc-linux-gnu; fixes 55 FAILs in jit.sum.
