Ard Biesheuvel 55f5af1871 MdePkg: fix ARM version of InternalMathSwapBytes64 ()
The ARM asm implementation of InternalMathSwapBytes64 () does
interesting things if bit 7 of operand r1 (upper 32 bits of the
input value) is set. After the recursive swap, bit 7 ends up in
the sign bit position, after which it is right shifted with sign
extension, and or'ed with the upper half of the output value.

This means SwapBytes64 (0x00000080_00000000) returns an incorrect
value of 0xFFFFFFFF_80000000.
