OvmfPkg: QemuVideoDxe: the VBE shim needs no 64-bit shifts (VS2010)
The SegmentC local variable has type EFI_PHYSICAL_ADDRESS for (justified)
style reasons. However, the 64-bit bit-shifts that it undergoes result in
intrinsic calls when built with VS2010 for Ia32 / NOOPT.
The concrete value of SegmentC, 0xC0000, and the results of the bitops
that are based on it, are statically computeable. Cast SegmentC to UINT32
before subjecting it to bitwise operations; we can see in advance that
this won't lead to range loss.
