At the start of ISel lowering of kernel function K:

[1] Collect all the LDS globals, say, LDSSet, which are used within the kernel K.
[2] Fix the natural alignment of all the LDS globals from LDSSet.
[3] Sort LDS globals from LDSSet first by their size and then by their alignment order.
[4] Allocate memory for LDS globals from LDSSet in the above sorted order.
