Parser: Inline expr pragmas with parenthesis
Parser: Inline expr pragmas with parenthesis

Previously pragmas could be attached only to whole statements, this change
allows attaching pragmas to inline statements, eg.:

  template rewriteAdd{a + b}(a: expr, b: expr): expr =
    ({.noRewrite.}: a + b) + 1

Code above will cause a + b to be rewritten once, because rewriteAdd attaches
{.noRewrite.} to resulting a + b expr.
