ARC can use odd-even double register pairs in some selected
instructions. Although the GNU assembler doesn't allow even-odd
registers to be used, there may be cases when the disassembler is
presented with such situation. This patch add a test and detects such
cases.

This is a followup to "binutils nm testsuite tidy". Since the perror
in binutils_assemble has been removed, we need to take more care in
failure paths.
The patch also fixed a number of .exp files that have multiple tests,
where an assembly failure returns from the .exp file. In most cases
it is nicer to attempt all tests.
* testsuite/binutils-all/ar.exp (unique_symbol): Don't run AR
if assembly fails.
* testsuite/binutils-all/arc/objdump.exp (check_assembly): If
objfile is empty, fail test.
* testsuite/binutils-all/arm/objdump.exp: Don't return if assembly
fails for a test, continue on to other tests.
* testsuite/binutils-all/bfin/objdump.exp: Likewise.
* testsuite/binutils-all/hppa/objdump.exp: Likewise.
* testsuite/binutils-all/m68k/objdump.exp: Likewise.
* testsuite/binutils-all/vax/objdump.exp: Likewise.
* testsuite/binutils-all/size.exp: Likewise.
* testsuite/binutils-all/nm.exp: Likewise. Move PR12753 test.
* testsuite/binutils-all/objcopy.exp: Don't perror on assembly fail.
* testsuite/binutils-all/objdump.exp: Report assembly fails.
Force printing of the short/signed values using hexadecimal

There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'. In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.
This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because
CONST_STRNEQ ("fpud", "fpuda")
would be true. The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.
