1.0.0rc2

• BINARY_MULTIPLY and BINARY_POWER will assume the resulting integer is a big integer (not unboxed)
• Introduced two optimizations IntegerUnboxingMultiply and IntegerUnboxingPower which are applied at optimization level 2. Try level two if you work with integers, but at smaller values to see better performance.
• Pyjion will infer that range(n) generates integers in iterator to improve unboxing
• LOAD_BUILD_CLASS will infer a function type instead of Any (#42)
• Instruction graphs will include the name of fast locals
• Instruction graph const values are capped to 40 characters
• Added abstract types for all builtins (#339)
• pyjion.info() will now return a JitInfo object
• Optimization flags that were applied to a function during compilation are available in JitInfo.optimizations
• All optimizations are now runtime flags instead of compile-time features
• Unboxing PGC errors will raise pyjion.PyjionUnboxingError (ValueError) instead of ValueError
• Instruction graphs will show conditional branches (in orange)
• Fixed a bug in generators where mixed unboxed/boxed fast locals would yield the wrong values with PGC between the first and second compilation stages
• Fixed a de-optimization that happened in rc1 due to PGC asserting the abstract kind on the profiling phase and then always asserting that integers were big-integers
• Fixed a bug where unboxed locals were decrefing frame locals on yield
• Generators will not unbox fast locals for stability reasons
• Fixed a regression on unboxed integers, caused by PGC values being set as Any
• Assert return types for float object methods (as_integer_ratio, conjugate, is_integer, hex)
