* opt-functions.awk (var_type): New function.
(var_set): Use CLVC_STRING if var_type returns "const char *".
* opth-gen.awk: Use var_type to find out the types of variables.
Don't print comments above each "extern" definition.
* optc-gen.awk: Use var_type in the same way.
* opts.h (cl_var_cond): Rename to...
(cl_var_type): ...this. Add CLVC_STRING.
(cl_option): Make "flag_var" a "void *" pointer. Replace "var_cond"
with "var_type".
* opts.c (handle_option, option_enabled): Update after above name
change. Cast flag_var before using it. Handle CLVC_STRING.
* config/alpha/alpha.h (alpha_tls_size): Delete.
* config/alpha/alpha.c (alpha_tls_size, alpha_cpu_string)
(alpha_tune_string, alpha_tp_string, alpha_fprm_string)
(alpha_fptm_string, alpha_mlat_string): Delete.
(alpha_handle_option): Don't set the above variables here. Use the
integer argument to check the validity of -mtls-size=.
* config/alpha/alpha.opt (mcpu=, mtune=, mfp-rounding-mode=)
(mfp-trap-mode=, mtrap-precision=, mmemory-latency=): Add Var()s.
(mtls-size=): Likewise. Convert to a UInteger and initialize the
variable to 32.

(arc_data_string, arc_rodata_string): Delete.
(arc_handle_option): Don't set the above variables here.

(target_float_abi_name, target_abi_name, structure_size_string)
(arm_pic_register_string): Delete.
(arm_handle_option): Don't set the above variables here, except
in the handling of -mhard-float and -msoft-float.
* config/arm/arm.opt (mabi=, mfloat-abi=, mfp=, mfpe=, mfpu=)
(mpic-register=, mstructure-size-boundary=): Add Var()s.
* config/ia64/ia64.h (ia64_tls_size): Delete.
* config/ia64/ia64.c (ia64_tls_size): Delete.
(ia64_handle_option): Treat -mtls-size= as a UInteger option,
reading the integer argument from the "value" parameter. Don't
set ia64_tls_size here.
* config/ia64/ia64.opt (mtls-size=): Turn into a UInteger option.
Add Var() and Init().
* config/m32r/m32r.h (m32r_cache_flush_func): Delete.
(m32r_cache_flush_trap): Delete.
* config/m32r/m32r.c (m32r_cache_flush_func): Delete.
