Allow the static chain to be set from C

We need to be able to set the static chain on a few calls within the
Go runtime, so expose this with __builtin_call_with_static_chain.

        * c-family/c-common.c (c_common_reswords): Add
        __builtin_call_with_static_chain.
        * c-family/c-common.h (RID_BUILTIN_CALL_WITH_STATIC_CHAIN): New.
        * c/c-parser.c (c_parser_postfix_expression): Handle it.
        * doc/extend.texi (__builtin_call_with_static_chain): Document it.

From-SVN: r217771

Allow the front-end to create calls with a static chain

And, at the same time, allow indirect calls to have a static chain.
We'll always eliminate the static chain if we can prove it's unused.

        * calls.c (prepare_call_address): Allow decl or type for first arg.
        (expand_call): Pass type to prepare_call_address if no decl.
        * gimple-fold.c (gimple_fold_call): Eliminate the static chain if
        the function doesn't use it; fold it otherwise.
        * gimplify.c (gimplify_call_expr): Gimplify the static chain.
        * tree-cfg.c (verify_gimple_call): Allow a static chain on indirect
        function calls.

From-SVN: r217770

Make TARGET_STATIC_CHAIN allow a function type

As opposed to always being a decl.  This is a prerequisite
to allowing the static chain to be loaded for indirect calls.

        * targhooks.c (default_static_chain): Remove check for
        DECL_STATIC_CHAIN.
        * config/moxie/moxie.c (moxie_static_chain): Likewise.
        * config/i386/i386.c (ix86_static_chain): Allow decl or type
        as the first argument.
        * config/xtensa/xtensa.c (xtensa_static_chain): Change the name
