Fix MSVC shift warnings in IR vector bounds checks

Make the conversion of IR_VECTOR_LENGTH to int64_t explicit in the REPLACE and EXTRACT folding rules. The vector length fits in 32 bits, but MSVC warns when its shifted value is implicitly widened for comparison (C4334), breaking builds with /WX.

Keep the fix as a bundled-source patch so the IR import remains reproducible.
