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.

- allowing true forward references (which will always assume the referenced
symbols have at the point of use) through the new .eqv pseudo-op and the
new == operator
- disallowing changing .equiv-generated equates (so that the protection this
provides is both forward and backward)
- snapshotting equates when their value gets changed so that previous uses
don't get affected by the new value.
- allowing expressions in places where absolute expressions (or register
names) are needed which were not completely resolvable at the point of
their definition but which are fully resolvable at the point of use
In addition it fixes PR/288.
