compiler: fix buglet in lshift type determination

    It's possible to construct an lshift expression using unsafe.Sizeof
    that is technically a compile-time constant but can't be evaluated
    without going through backend methods. In this case, insure that
    Type::make_non_abstract_type is called on the numeric operand of the
    shift (as opposed to leaving as abstract), to avoid an assert later on
    in the compiler flow.

compiler: handle >32bit exponent in Ldexp

    Libgo's implementation of math.Ldexp declared the libc "ldexp" as
    taking an 'int' exponent argument, which is not quite right for 64-bit
    platforms (exp arg is always int32); this could yield incorrect
    results for exponent values outside the range of Minint32/Maxint32.
    Fix by upating the type for the libc version of ldexp, and adding
    guards to screen for out-of-range exponents.

    Fixes #21323.
