If an inlined kernel is called in a loop, the launch point alloca would
lead to increasing stack usage every time the kernel is invoked. This
could make the application run out of stack space and crash. This problem
is fixed by using the alloca insertion point while creating the alloca instruction.

The indeces of the dependent loops are properly ordered, just start from
1, so need just subtract 1 to get correct loop index.
