[AArch64][NFC] Deleted llvm/test/Analysis/CostModel/AArch64/splat-load.ll test

[vporpo]

Summary

This test is no longer necessary as it is a subset of:
llvm/test/Analysis/CostModel/AArch64/shuffle-load.ll

[dmgreen]

Cheers. LGTM. This probably didn't need review, you would have been fine just committing it :)

-; This test checks that the cost of a splat-load shuffle is correctly detected
-; as 0, because the combined load + broadcast is lowered to a `ld1r` instruction.
-;
-; NOTE: The code in this test is a hack. Since TTI cannot currently detect a
-; proper broadcast pattern from a scalar load (like the one that follows),
-; we use a vector load as the shuffle's operand to trigger the pattern.
