Revert "Fix incorrect 'unreachable code' error in SkSL" This reverts commit 67d2d73d063ca416993e8ed5b4101150bf4b1ca7. Reason for revert: Triggers errors in some shaders. Original change's description: > Fix incorrect 'unreachable code' error in SkSL > > This trades one error for another (a potential for incorrect use of > unassigned variables). False-positives for unassigned variables are > straightforward to workaround (and produce code that still looks > reasonable). Working around unreachable code errors is tricky, and > likely to produce non-idiomatic code. This change also makes the data > flow analysis of all loop constructs more similar - for loops were > behaving very differently from while loops. > > Note that this effectively a revert of: > https://skia-review.googlesource.com/c/skia/+/18121/ > > Change-Id: Ib85d90b22cac8addfb106459c0a5f5616a89c3eb > Reviewed-on: https://skia-review.googlesource.com/c/skia/+/344957 > Reviewed-by: Ethan Nicholas <ethannicholas@google.com> > Commit-Queue: Brian Osman <brianosman@google.com> TBR=brianosman@google.com,ethannicholas@google.com,johnstiles@google.com Change-Id: I84b93cc7f9309446dcc0e949e90908df31a1ff9c No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://skia-review.googlesource.com/c/skia/+/345119 Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: Brian Osman <brianosman@google.com> 2020-12-16 18:21:05 +00:00			`4 errors`
