6. Shift instructions

The simple scalar shifts on PPC64 expect a shift count that fits in 5 bits for
32-bit values or 6 bit for 64-bit values. If the shift count is a constant value
greater than the max then the assembler sets it to the max for that size (31 for
32 bit values, 63 for 64 bit values). If the shift count is in a register, then

	nilfunc          check for useless comparisons between functions and nil
	printf           check consistency of Printf format strings and arguments
	shift            check for shifts that equal or exceed the width of the integer
	sigchanyzer      check for unbuffered channel of os.Signal
	slog             check for invalid structured logging calls

	sign = uint32(b >> 63)
	exp = int32(b>>52) & mask
	mantissa = b & fracMask

	if exp == 0 {
		// Normalize value if subnormal.
		shift := uint(bits.LeadingZeros64(mantissa) - 11)
		mantissa <<= shift
		exp = 1 - int32(shift)
	} else {
		// Add implicit 1 bit
		mantissa |= 1 << 52
	}
	return
