Subject: [PATCH 6/6] Implement the bs_create_bin instruction

Implement the bs_create_bin instruction for the JITs and the emulator.

Consider this example module:

-module(foo).
    -export([bin/2, int/2, float/2, var_int/2]).

bin(A, B) -> <<A/binary, B/binary>>.
    int(A, B) -> <<A/integer, B/integer>>.
    float(A, B) -> <<A/float, B/float>>.
    var_int(A, Size) -> <<A:Size>>.

With the extended error information introduced in this commit, failures to build
binaries will be reported like this:

1> c(foo).
    {ok,foo}
    2> foo:bin(2, <<>>).
    ** exception error: construction of binary failed
         in function  foo:bin/2 (foo.erl, line 4)
            *** segment 1 of type 'binary': expected a binary but got: 2
    3> foo:bin(<<>>, 42).
    ** exception error: construction of binary failed
         in function  foo:bin/2 (foo.erl, line 4)
            *** segment 2 of type 'binary': expected a binary but got: 42
    4> foo:bin(<<>>, <<1:1>>).
    ** exception error: construction of binary failed
         in function  foo:bin/2 (foo.erl, line 4)
            *** segment 2 of type 'binary': the size of the value <<1:1>> is not a multiple of the unit for the segment
    5> foo:int(a, 42).
    ** exception error: construction of binary failed
         in function  foo:int/2 (foo.erl, line 5)
            *** segment 1 of type 'integer': expected an integer but got: a
    6> foo:float(<<>>, <<>>).
    ** exception error: construction of binary failed
         in function  foo:float/2 (foo.erl, line 6)
            *** segment 1 of type 'float': expected a float or an integer but got: <<>>
    7> foo:var_int(42, -1).
    ** exception error: construction of binary failed
         in function  foo:var_int/2 (foo.erl, line 7)
            *** segment 1 of type 'integer': expected a non-negative integer as size but got: -1
    8> foo:var_int(42, a).
    ** exception error: construction of binary failed
         in function  foo:var_int/2 (foo.erl, line 7)
            *** segment 1 of type 'integer': expected a non-negative integer as size but got: a
    9> foo:var_int(42, 1 bsl 64).
    ** exception error: construction of binary failed
         in function  foo:var_int/2 (foo.erl, line 7)
            *** segment 1 of type 'integer': the size 18446744073709551616 is too large

Closes #4971.
