Fold And/Or into the same in-place sp-rewrite shape as Not/LessEqual.
Both args must be tLogical — short-circuit on the raw scalar field so
the hot path is pure integer arithmetic + two cached bool Values.

Mirror the treatment LessEqual already got onto Equal/NotEqual/Less/
Greater/GreaterEqual — rewrite sp directly, check the type tag for
Int==Int in the hot branch, short-circuit to cachedTrue/cachedFalse
without a second method call. Keeps the slow fallback for mixed /
string / date types.
Bench movement is minor on SQL paths (WHERE is already pcode and
skips these ops); the win is on PRG comparisons that cache-miss out
of the pcode path — FOR-condition short forms, IF chains, etc.

value.go:
- cachedNil, cachedTrue, cachedFalse: pre-built constant Values
- MakeBool()/MakeNil(): return cached (zero allocation)
- smallInts[256]: pre-built integers 0-255 (skip intExpLen loop)
- MakeInt(): fast path for 0-255
thread.go:
- pop(): use cachedNil for GC help (no MakeNil() call)
ops_compare.go:
- LessEqual(): inline Int-Int fast path (skip valueCompare)
Direct scalar comparison with cached bool result
- Not(): inline logical fast path (skip IsLogical+AsBool)
- PopLogical(): inline type check + scalar read
Impact: these functions called millions of times in FOR/DO WHILE loops.
