a841bdf5d3 Fix PR17493, attempted output of *GAS `reg' section* symbol 
The write.c change is to make gas report an error if reg_section
symbols should leak in future.  The tc-i386.c change is the real fix.

Note that the error isn't the most helpful, "redefined symbol cannot
be used on reloc", but I'm not inclined to improve what is really an
internal gas error.  reg_section symbols shouldn't leak..

85024cd8bc Run write_object_file after errors 
This is to fix unitialised memory access when printing listings.
Many targets don't initialise parts of insn frags or data frags that
have fixups, relying on md_apply_fix to finalise the frag.  Which is
fine normally, but means we need to run write_object_file after
errors, for listings.  Otherwise MALLOC_PERTURB_=1 causes errors like:
x86_64-linux  +FAIL: i386 mpx-inval-1
x86_64-linux  +FAIL: i386 inval-equ-1
x86_64-linux  +FAIL: i386 x86-64-mpx-inval-1

Running write_object_file after errors requires some tweaking to the
testsuite, since we then get extra errors reported from md_apply_fix.

62ebcb5cbe gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW 
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables.  That's OK, but not best
practice.  tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants.  This patch fixes both of these warts.
