Mention the purpose of the BICri tests added by r318398, as requested in
post-commit review.

%0(s32) = COPY %r0
; CHECK: [[VREGX:%[0-9]+]]:gpr = COPY %r0
+ ; This test and the following ones are a bit contrived, since they use a
+ ; G_XOR that can be constant-folded. They exist mostly to validate the
+ ; TableGen pattern that defines BICri. We also have a pattern for matching a
+ ; G_AND with a G_CONSTANT operand directly, which is the more common case,
+ ; but that will be covered by different tests.
%1(s32) = G_CONSTANT i32 192
%2(s32) = G_CONSTANT i32 -1
