Emit errors when always_inline functions cannot be inlined in -O0 mode.
* tree-inline.c (expand_call_inline): Allow the error to be flagged
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.
