Fix spurious warnings from unwise condition order in inlined code
These are both conditions having the form (and A B) where A is
side-effect-free and B may be known to be nil at compile time.
The compiler will then warn about A being useless and thrown away.
The fix is to test B first.

Test `(not no-enter-cache)` first.

Lexical variables bound to a constant value (symbol, number or string)
are substituted at their point of use and the variable then eliminated
if possible. Example:
(let ((x (+ 2 3))) (f x)) => (f 5)
This reduces code size, eliminates stack operations, and enables
further optimisations. The implementation is conservative, and is
strongly curtailed by the presence of variable mutation, conditions
and loops.
