Consecutive numbers can make it difficult to combine assembly output from
different compiler runs, which is done by the check/checkfile scripts to find
bugs in the SPEC suite. If the number of basic blocks of a function changed
between compiler runs, the assembler will likely complain about duplicate labels.
Leaving a bit more space, e.g. 100, is a pragmatic fix.
be_emit_char('\n');
be_emit_write_line();
be_emit_char('\n');
be_emit_write_line();
+
+ next_block_nr += 100;
