RFR: 8345172: x86: Some CPU feature asserts are declared as 32-bit only

[Aleksey Shipilev]

Noticed this while cleaning up the 32-bit x86 code. We baseline our 64-bit x86 to be at least UseSSE=2. Therefore we still need to check for features UseSSE > 2. I have found a few places where we do NOT_LP64 for these checks. I checked other `VMVersion::supports_*()` uses, and I think these are the only two outliers.
