[X86] Bugfix for rL349334

[yubing]

Summary

Since the width of a bit field cannot exceed the width of the underlying type, we should change fraction's type to long long for ia32.

119–121

Have you confirmed this works? Would it be better to change all 3 members to use unsigned long long?

LGTM - cheers
