  [flang][OpenMP] Lowering support for atomic capture

This patch adds lowering support for atomic capture operation. First is
created a region (without any operand) for the atomic capture operation.
Then based on one of the following configurations...

	1. [update-stmt, capture-stmt]
	2. [capture-stmt, update-stmt]
	3. [capture-stmt, write-stmt]
... the lowering proceeds by creating these individual operations inside
the atomic capture's region.
