    PR30308, infinite recursion in i386_intel_simplify

    This patch exposes the symbol "resolving" flag for use in
    i386_intel_simplify, not only preventing infinite recursion on the
    testcase in the PR but also more complicated cases like:

     .intel_syntax
     b = a
     a = b
     mov eax, [a]

            PR 30308
            * symbols.c (symbol_mark_resolving, symbol_clear_resolving),
            (symbol_resolving_p): New functions.
            * symbols.h: Declare them.
            * config/tc-i386-intel.c (i386_intel_simplify): Delete forward
            declaration.  Formatting.
            (i386_intel_simplify_symbol): Use resolving flag to prevent
            infinite recursion.
