### Compilation failed:

error: 1: integer is out of range for type 'uint': -1
uint s, z = s.0s.0s - 1;
            ^^^^^^^^^^^
error: 1: expected 'uint', but found 'uint2'
uint s, z = s.0s.0s - 1;
            ^^^^^^^^^^^
2 errors
Fix for fuzzer-discovered error with negation. Yesterday's negation-related changes (http://review.skia.org/464123) exposed a flaw that the fuzzer was able to exploit. We were previously able to assume that `simplify_negation` would always return a non-null expression; in some cases, that is no longer true.

Added range highlighting to SkSL error reports SkSL errors now identify the specific range of code they are describing, rather than just the line number.
