assembler_solaris_x86.cpp uses r8-r11 for 32-bit compilation

[Vladimir Kozlov]

Hi, Tomek

Note that Oracle does not support 32-bit JDK(JVM) on Solaris since jdk8.
Why you need 32-bit JVM on Solaris?

As much as we want 8130212 changes be done for 32-bit too but it is not 
as simple as it looks. Putting #ifdef is not enough for 32-bit code 
works correctly. And it will rot anyway since we don't test it.

Regards,
Vladimir
