RenderScript command for printing allocation information

This patch adds a new command 'language renderscript allocation list' for printing the details of all loaded RS allocations.

In order to work out this information lldb JITs the runtime for the data it wants.
This has a penalty of a couple seconds latency, so is only done once for each allocation and the results cached.

If the user later wants to recalculate this information however, they can force lldb to do so with the --refresh flag.
