`match()` can only return for non-empty vectors, but at least in non-LTO builds that isn't clear to the compiler. Help it out. This is a minor but measurable speedup on my machine (but less than what we might've lost in https://reviews.llvm.org/D100818#2764272 -- bot note higher N on this measurement here, so higher confidence here): % ministat at_main at_branch x at_main + at_branch N Min Max Median Avg Stddev x 30 3.9243979 4.0395119 3.987375 3.9826236 0.027567796 + 30 3.8495831 4.0009291 3.931325 3.9347135 0.037832878 Difference at 95.0% confidence -0.0479101 +/- 0.0171102 -1.20298% +/- 0.429622% (Student's t, pooled s = 0.0331007) No behavior change. Eventually we should apply these lists at symbol parse time instead of every time shouldExportSymbol() though :) Differential Revision: https://reviews.llvm.org/D102655 |

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
