John Stiles 34c098d7f8 Add SkSL test demonstrating missed optimization with +=. ... Currently, SkSL is able to constant-propagate `x = x + constant` into `x = constant` when the starting value of x is known. However, it is not able to do the same optimization for `x += constant`. This test demonstrates that once += is encountered, we lose track of x's value and can no longer propagate its value. (This is equally true of all the op-assignment operators, += -= *= /= etc.) Change-Id: I3523e96baf9a73982cf3b09f0d23b95adacf106b Bug: skia:11192 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/368248 Auto-Submit: John Stiles <johnstiles@google.com> Commit-Queue: Brian Osman <brianosman@google.com> Reviewed-by: Brian Osman <brianosman@google.com>		2021-02-09 19:17:26 +00:00
