[AArch64] Disable LDP/STP for quads Disable LDP/STP for quads on Exynos M1 as they are not as efficient as pairs of regular LDR/STR. Patch by Abderrazek Zaafrani <a.zaafrani@samsung.com>. llvm-svn: 266223

[AArch64] Switch regression tests to test features not CPUs Summary: We have switched to using features for all heuristics, but the tests for these are still using -mcpu, which means we are not directly testing the features. This converts at least some of the existing regression tests to use the new features. This still leaves the following features untested: merge-narrow-ld predictable-select-expensive alternate-sextload-cvt-f32-pattern disable-latency-sched-heuristic Reviewers: mcrosier, t.p.northover, rengolin Subscribers: MatzeB, aemerson, llvm-commits, rengolin Differential Revision: http://reviews.llvm.org/D21288 llvm-svn: 273271
