Marina Yatsina 67b39f3e9e Fix for PR29010 
This is a fix for https://llvm.org/bugs/show_bug.cgi?id=29010
Root cause of the bug is that the register class of the machine instruction operand does not fully reflect if this registers that can be allocated.
Both for i386 and x86_64 the operand's register class is VR128RegClass and thus contains xmm0-xmm15, though in i386 we can only use xmm0-xmm8.
In order to get the actual allocable registers of the class we need to use RegisterClassInfo.
