    [stubs] Convert DoubleToIStub and MathPowStub to builtins · a3b60675
    jgruber authored
    This is mostly a simple copy & paste of the stub implementation from
    code-stubs-arch.cc to builtins-arch.cc.
    
    The conversion allows removal of a special case for the DoubleToIStub
    within the compiler & wasm pipelines, and also makes the following
    builtins isolate-independent (in conjunction with
    https://crrev.com/c/1006581):
    
    TFC BitwiseAnd
    TFC BitwiseOr
    TFC BitwiseXor
    TFC Exponentiate
    TFC ShiftLeft
    TFC ShiftRight
    TFC ShiftRightLogical
    TFJ AtomicsAdd
    TFJ AtomicsAnd
    TFJ AtomicsCompareExchange
    TFJ AtomicsExchange
    TFJ AtomicsLoad
    TFJ AtomicsOr
    TFJ AtomicsStore
    TFJ AtomicsSub
    TFJ AtomicsXor
    TFJ MathClz32
    TFJ MathImul
    TFJ MathPow
    TFJ NumberParseInt
    TFJ StringFromCharCode
    TFJ TypedArrayFrom
    TFJ TypedArrayOf
    TFJ TypedArrayPrototypeMap
    
    Drive-by: dead code removal & TODOs in code-stubs.h.
