* Makefile.in (BUILD_RTL): Move build/read-md.o to...
(BUILD_MD): ...this new variable.
(simple_generated_rtl_h, simple_generated_rtl_c): New variables
that include the old contents of simple_generated_h and
simple_generated_c.
(simple_generated_h, simple_generated_c): Include them. Add
insn-constants.h.
(s-%): Make simple_generated_{h,c} stamps depend on $(MD_DEPS)
and simple_generated_rtl_{h,c} stamps depend on insn-conditions.md.
Remove these dependencies from the main rule and include
insn-conditions.md in the command line only if it appears
in the dependency list.
(insn-constants.h, s-constants): Delete.
(build/genconstants.o): Don't depend on $(RTL_BASE_H), $(GTM_H)
or gensupport.h.
(build/genmddeps.o): Likewise.
(genprogrtl): New variable that contains everything from genprogmd
except mddeps and constants.
(genprogmd): Redefine in terms of genprogrtl. Make these programs
depend on $(BUILD_MD)
(genprog): New variable. Make these programs depend on
$(BUILD_ERRORS).
* genmddeps.c: Don't include tm.h, rtl.h or gensupport.h.
(main): Use read_md_files instead of init_rtx_reader_args.
* genconstants.c: As for genmddeps.c.
* read-md.h (read_skip_construct): Declare.
* read-md.c (read_skip_construct): New function.
(handle_file): Allow a null handle_directive, skipping the
construct if so.
(parse_include): Update the comment accordingly.
