[PATCH] compiler, clang: Add always_inline attribute to inline

[Prasad Sodagudi]

Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused
static inline functions") re-defining the 'inline' macro but
__attribute__((always_inline)) is missing. Some compilers may
not honor inline hint if always_iniline attribute not there.
So add always_inline attribute to inline as done by
compiler-gcc.h file.
