Previously, we only emitted compact branches; however, the offset range of these branches is too small for many real world shaders. This patch implements support for emitting extended branches and switches to always using them for control flow. This incurs a code size and possibly performance penalty, but expands the range of working shaders and provides opportunity for further optimization. Support for emitting compact branches is retained but this code path is presently unused. In the future, we'll want to heuristically determine which type of branch should be emitted for optimal codegen. Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io>
