Introduce Stmt\Block

Stmt\Block will be created for { $a; } style blocks, unless these
occur directly inside some structure that is usually combined
with a block.

{ $b; } will become a Stmt\Block.

an Identifier wrapper. Identifier implement __toString(), so that
outside of strict-mode many things continue to work without changes.

This sets Declare->stmts to null for the body-les
