0.9.15.27: compiler-macro expansion for FUNCALL forms & bugfixes
 * Refactor the compiler to first consider special forms and
   compiler-macro expansions before other options. (Necessary for the
   rest.)

 * FUNCALL forms now get compiler-macro expansion when applicable.

 * COMPILER-MACRO-FUNCTION takes shadowing by local functions into
   account.

 * Local INLINE declarations no longer inhibit compiler-macro
   expansion.

 * Tests.
