In tc-arc.h we redefine constants that are also defined in the
include/opcode/arc.h header file. The problem is that changing one
without changing the other resulting in strange crashes.
We could comment both locations to stress the importance of remembering
to update the other location too, or we could just include the
opcode/arc.h header file into the assembler.
Given that other targets include their opcode/ARCH.h header file, and
only having a single definition, where possible, is usually the safest
solution, that's what I switch too with this commit.

Providing declarations in tc.h points out that alpha wasn't properly marking
FLT_CHARS as const. We can also get rid of the confusing redefinition of
X_CHARS to mmix_x_chars. Finally we can get rid of some now redundant
declarations of these constants.

Xtensa uses it in several macros passing it a literal string, so its convenient
for the argument type to be const char *. However some of the code in
symbols.c seems to assume tc_canonicalize_symbol_name () will return a non
const pointer, and some other target's implementations even modify the
argument, so it seems best to return a char * which means casting away const on
the argument when we return it instead of another string.

parse_ldconst () takes a char ** as a in / out argument, and sometimes points
args[0] to a constant string. Then in some cases after parse_ldconst ()
returns md_assemble () twiddles the contents of arg[0]. So it seems like
it would take some work to avoid these casts, and its not really clear
that work is worth it.

* config/tc-i960.c (parse_ldconst): Cast to char * when assigning to

For these targets its not clear how md_assemble can usefully be split up so
that part can take const char *. There is also a fair number of targets that
need md_assemble () to take a char *, so we can't easily make the argument
const. So since there isn't many callers it seems easiest to just add a couple
of casts.

get_symbol_name () returns a char * in a out arg, which means we need to cast
to assign a literal to the variable passed to get_symbol_name (). It seems
like better APIs than get_symbol_name () could be provided, but that seems like
a fair amount of work so just casting seems to be the betterthing to do for
now.

various places either directly or indirectly set input_line_pointer to point at
a literal. Currently lots of places modify the string input_line_pointer
points at, so making it const isn't easy. Since most if not all of these
places assign to input_line_pointer to parse an expression it would probably be
best to add ways to generate and deal with expressions that doesn't involve
parsing strings, but for now adding some casts seems easiest.

In the SPARC V9 (and later) versions of the SPARC specification, the
section C.1.1 "Register Names" specifies that:
"asr_reg. An asr_reg is an Ancillary State Register name. It may have
one of the following values:
%asr16-%asr31"
The rationale of having this restriction was that the registers from 16
to 31 are reserved to implementations, and are therefore "non-V9". It
also assumes that the existing ASR registers in the range 0..31 will
have their own names such as %y, that can be used to access such
registers.
However, this is problematic. When a new ASR register is introduced,
such as %mcdper a.k.a. %asr14, it is useful to be able to use %asr14 in
order to not depend on the latest version of the assembler.
The Solaris assembler is lax and allows to assembly instructions
referring to %asr0 to %asr31. This patch makes the GNU assembler to
mimic that behavior.

frag_var () assigns its last argument to frag::fr_opcode, and it turns out
some targets modify the string that points to. However it appears niether the
generic code or the microblaze code modifies what fr_opcode points to, so this
code should be safe. So we unfortunately need to cast to char * when passing
an argument to frag_var () but otherwise microblaze can itself point to these
strings with const char *.

I'm not sure the string it returns is particularly useful, or better than the
string returned by other atof implementations on failure, but given the others
return a localized string it seems like this one should too.

if the condition is true then we know that str already points to a'\0' in the
string passed to the function. Since we know the latter part of the function
doesn't modify that string, and str already points to a null byte there's no
point in changing str to point to a literal empty string.
