    Emit errors when always_inline functions cannot be inlined in -O0 mode.

            * tree-inline.c (expand_call_inline): Allow the error to be fla=
gged
            in early inline pass.
            * ipa-inline.c (inline_always_inline_functions): Pretend
always_inline
            functions are inlined during failures to flag an error.
            * gcc.target/i386/inline_error.c: New test.
            * gcc.c-torture/compile/pr44043.c: Fix test to expect an error.
            * gcc.c-torture/compile/pr43791.c: Fix test to expect an error.
