Perform whole-shader analysis to determine usage limits.
Use these limits to allocate compile time and runtime arrays.

Removes the constants:
	MAX_SHADER_NESTED_LOOPS
	MAX_SHADER_NESTED_IFS
	MAX_SHADER_CALL_STACK_SIZE

Also switched to using dynamic containers to remove the MAX_SHADER_CALL_SITES limit, which I believe to have been buggy and broken.
