[15] RFR (M): 8238681: Make -XX:UseSSE flag x86-specific

[Vladimir Kozlov]

http://cr.openjdk.java.net/~vlivanov/8238681/webrev.01/ gives me "404 - Not Found"

Looking on webrev.00.

compiler/c1/Test6579789.java and compiler/c1/Test6855215.java use UseSSE flag without @requires.

Graal/JVMCI supports only 64 bit x86 and access UseSSE only in 'AMD64' specific files. So it is fine.

Otherwise changes seems good.

Thanks,
Vladimir
