Delete a test that is no longer relevant.
According to PR2536, the old spiller had trouble with the IMPLICIT_DEF in this
code:
%reg1028<def> = MOV16rm %reg0, 1, %reg0, <ga:g_5>, Mem:LD(2,2) [g_5 + 0]
%reg1039<def> = IMPLICIT_DEF
%reg1038<def> = INSERT_SUBREG %reg1039, %reg1028, 2
%reg1025<def> = AND32ri %reg1038, 65534, %%EFLAGS<imp-def>
However, today we emit a zero-extending load instead:
%vreg10<def> = MOVZX32rm16 %noreg, 1, %noreg, <ga:@g_5>, %noreg; %mem:LD2[@g_5] GR32:%vreg10
%vreg0<def> = AND32ri %vreg10, 65534, %%EFLAGS<imp-def,dead>; %GR32:%vreg0,%vreg10
This makes the test pointless since it no longer creates the spiller hazard.
