don't declare header-defined functions both static and inline

Many functions defined in our headers are declared 'static inline' which
is a C idiom whose use predates our move to C++ as the implementation
language.  But in C++ the inline keyword is more than just a compiler
hint, and is sufficient to give the function the intended semantics.
In fact declaring a function both static and inline is a pessimization
since static effectively disables the desired definition merging
behavior enabled by inline, and is also a source of (harmless) ODR
violations when a static inline function gets called from a non-static
inline one (such as tree_operand_check calling tree_operand_length).

This patch mechanically fixes the vast majority of occurrences of this
anti-pattern throughout the compiler's headers via the command line

  sed -i 's/^static inline/inline/g' gcc/*.h gcc/*/*.h

There's also a manual change to remove the redundant declarations
of is_ivar and lookup_category in gcc/objc/objc-act.cc which would
otherwise conflict with their modified definitions in objc-act.h
(due to the difference in staticness).

Besides fixing some ODR violations, this speeds up stage1 cc1plus by
about 2% and reduces the size of its text segment by 1.5MB.
