Malte Ubl 2162b0af65 Identity bitwise forms over proven int32 operands return the operand

`x | 0`, `x ^ 0`, `x & -1`, `x << 0`, `x >> 0` (and `x >>> 0` for a
uint32) over an operand the integer range analysis proves an int32 now
return the operand's number and its integer views instead of converting
to i32 and back: ranges exclude -0, so the result is the operand bit for
bit. The range analysis computes bitwise result ranges from the operand
ranges (exact ToInt32/ToUint32 views, shift-count ranges) instead of the
blanket int32 range, so `(n & 0xff) | 0`, `s.length >> 1` or `x >>> 1`
keep tight bounds for later integer consumers.
