There was a microoptimization for smoothing srtt with bitshifts. Revert
the code to use * 98 / 100, it doesn't really make that difference on
modern CPUs, for comparison here:
muldiv:
imul eax, edi, 98
imul rax, rax, 1374389535
shr rax, 37
ret
shift:
mov eax, edi
sal eax, 9
sub eax, edi
shr eax, 9
ret
