This allows generators to have more control over the placement of suffix. Needed for ‘if’ blocks and function calls which require their suffix code to be somewhere other than the end.
Also, add loop’s prefix to ‘break’ blocks, since the loop’s suffix will be the next statement hit.
Also, reuse procedures_callreturn generator for procedures_callnoreturn.
Also remove need to manually indent INFINITE_LOOP_TRAP. This is a breaking change for Python users of this property. However, very few users of this property exist, given that the existing code breaks if the block ID has a $ in it (also fixed in this PR).
* fix indentation for the return statement in function blocks that return a value
* Fix hard-coded autoindent, and swap it for Blockly.PHP.INDENT
* Fix hard-coded 2 spaces indent and use language-appropriate global indent
