CHECK_IMPURE and PURE_P speedup

* src/intervals.c (create_root_interval):
Do CHECK_IMPURE only for strings; not needed for buffers.
Prefer ! STRINGP to BUFFERP, for a tad more speed.
* src/puresize.h (CHECK_IMPURE, PURE_P):
Now inline functions instead of macros.
(PURE_P): Don’t use XPNTR; that is now the caller’s responsibility.
All callers changed.
(CHECK_IMPURE): New argument PTR, to save us the work of running XPNTR.
All callers changed.
