    i386/i386/fpu.h: Fix xrstor and xrstors macros
    
    xrstor and xrstors also take the xsave support bitmask.
    
    We were otherwise not necessarily properly reloading all the FPU state,
    thus leading to various subtle bugs, notably with glibc 2.33's
    ifunc-optimized memcpy etc.
    
    * i386/i386/fpu.h (xrstor, xrstors): Pass fp_xsave_support in EDX:EAX.
