Log:
[AArch64] add SLP test based on TSVC; NFC
This is a slight reduction of one of the benchmarks
that suffered with D43079. Cost model changes should
not cause this test to remain scalarized.

+; This test is reduced from the TSVC evaluation of vectorizers:
+; http://www.llvm.org/viewvc/llvm-project/test-suite/trunk/MultiSource/Benchmarks/TSVC/LoopRerolling-flt/tsc.c?view=log
+; Two loads and an fmul are expected to be vectorized to <2 x float>.
+; Otherwise, performance will suffer on Cortex-A53.
+; See https://bugs.llvm.org/show_bug.cgi?id=36280 for more details.
