Include simple interpolations in getValueText

When calculating `StringlikeLiteral.getValueText`, include results from
interpolations where we can determine their string value. For example:

    b = "b" # local variable
    D = "d" # constant

    "a#{b}c"     # getValueText() = "abc"
    "a#{b}c{D}"  # getValueText() = "abcd"
    /#a#{b}c{D}/ # getValueText() = "abcd"
