  Log Message:
  -----------
  [flang] Set LBOUND() folding for (x) expression as ones

Set LBOUND() constant folding for parentheses expr. as ones

Array bounds should not propagate throught omitted bounds specifications or
temporary variables - fix constant folding in case of Parentheses<T> expression
by explicitly returning array of ones (or scalar in case of DIM=).

Add set of tests for (x) bounds checks (w/ and w/o 'parameter' arrays)
