Adds a margin stripping string interpolator.

Currently only for compiler internal use.

Designed to avoid surprises if the interpolated values
themselves contain the margin delimiter.

Before:

    val bip = "\n  |.."

     s"""fooo
        |bar $bip
        |baz""".stripMargin

    "fooo
    bar
    ..
    baz"

After:

    sm"""fooo
        |bar $bip
        |baz"""

    "fooo
    bar
      |..
    baz"
