XSYMBOL eassume speedups

* src/lisp.h (XSYMBOL_WITH_POS_SYM, XSYMBOL): Help the compiler by using
eassume instead of eassert for XSYMBOL postconditions likely to be
useful for optimization later.  With gcc 13.2 -O2 x86-64 this improved
speed on my usual “compile all .el files” benchmark by 0.7% and shrank
the text size of Emacs by 0.09%.

(cherry picked from commit d202f1b9e74107c0e51c5d2fdbe094cbe1baaadb)
