vegorov@chromium.org f476d4d431 Allow uint32 value on optimized frames if they are consumed by safe operations. ... Safe operations are those that either do not observe unsignedness or have special support for uint32 values: - all binary bitwise operations: they perform ToInt32 on inputs; - >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side; - >>> shift: it performs ToUint32 on both inputs; - stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise"; - HChange: special support added for conversions of uint32 values to double and tagged values; - HSimulate: special support added for deoptimization with uint32 values in registers and stack slots; - HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.
