[PATCH] aarch32: add verification of Use*Intrinsics cmdline parameters

[Alexey Bakhtin]

Hi All,

Current implementation allows to enable SHA Intrinsics on the unsupported CPU and PrintFlagsFinal shows intrinsic are enabled.
It could be reproduced to run java with the following parameters:

"j2sdk-image/bin/java -client -XX:+UseSHA -XX:+PrintFlagsFinal -version" and parse output.
SHA intrinsics are not supported on ARMv7, but option -XX:+UseSHA results in 
bool UseSHA       := true       {product}

The same is for 
-XX:+UseSHA256Intrinsics
-XX:+UseSHA512Intrinsics
-XX:+UseSHA1Intrinsics

There are no bug for this issue yet.
Suggested fix is to add verification of intrinsics cmdline parameters in the src/cpu/aarch32/vm/vm_version_aarch32.cpp :

Thank you
