options.texi (Variable): Document.
* doc/options.texi (Variable): Document.
* optc-gen.awk, opth-gen.awk: Handle Variable records. Don't
generate target_flags declarations explicitly. Don't define
VarExists variables for the driver.
* common.opt (target_flags): New Variable record.
(flag_dump_unnumbered, flag_dump_unnumbered_links,
flag_var_tracking, flag_var_tracking_assignments,
flag_var_tracking_assignments_toggle): Don't mark variables with
VarExists.
* config/i386/i386.c (ix86_isa_flags): Don't define here.
* config/i386/i386.opt (ix86_isa_flags): Define here.
* config/mcore/mcore.c (mcore_stack_increment): Don't define here.
* config/mcore/mcore.opt (mcore_stack_increment): Don't mark with
VarExists.
* flags.h (flag_dump_unnumbered, flag_var_tracking): Remove.
* print-rtl.c (flag_dump_unnumbered, flag_dump_unnumbered_links):
Only define for generator programs.
