[Bug bootstrap/32617] New: explow.c references DECL_ALIGN of a FUNCTION_DECL

["geoffk at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In explow.c, there's this code:

    if (GET_CODE (x) == SYMBOL_REF)
      {
        align = BITS_PER_UNIT;
        if (SYMBOL_REF_DECL (x) && DECL_P (SYMBOL_REF_DECL (x)))
          align = DECL_ALIGN (SYMBOL_REF_DECL (x));
      }

If SYMBOL_REF_DECL(x) is a FUNCTION_DECL, DECL_ALIGN() does not have valid
data, so this code will cause the alignment of a function's MEM to be set to
random data.
