64bit set shift count overflow

[ayfomin]

When we use set type in a scheme with uint64 encoding type:

<set name="FlagsSet" encodingType="uint64">
    <choice name="Bit0" description="Bit 0">0</choice>
    <choice name="Bit35" description="Bit 35">35</choice>
</set>

sbe-all generates CPP code like this:

static bool bit35(const std::uint64_t bits)
{                                           
    return (bits & (1u << 35u)) != 0;
}

which causes warning in gcc:

FlagsSet.h:255:31: warning: left shift count >= width of type [-Wshift-count-overflow]
         return (bits & (1u << 35u)) != 0;

Here is the value of right operand - 35u is greater to the number of bits in the left operand 1u - 32 bits.

Could somebody help to fix it, please?
