x86: Narrow UseAVX and UseSSE flags

    Description

      The UseSSE and UseAVX has wider ranges than what values are actually allowed. Narrow this down, along with the flag types.

      Since these two flags are used in more than a thousand places narrowing the types has a tiny but measurable impact on binary size (~4.1kb size reduction of libjvm.so on linux-x64)
