Add the ability to set breakpoints on named RenderScript reductions
- Add new `lldb_private::lldb_renderscript::RSReduceBreakpointResolver` class that can set breakpoints on kernels that are constituent functions of named reduction groups. Also support debugging of subsets of the the reduction group with the `-t, --function-role` flag which takes a comma-separated list of reduction function types outconverter,combiner,initializer,accumulator (defaults to all) - Add 2 new helper methods to `RenderScriptRuntime`, 1. `CreateReductionBreakpoint(name, types)`: instantiates a new RSReduceBreakpointResolver and inserts that resolver into the running process. 2. `PlaceBreakpointOnReduction`: which is a public helper function. - hook up the above functionality to the command-line with new `CommandObject*` classes that handle parsing of function roles and dispatch to the runtime. These are namespaced under the snappy `language renderscript reduction breakpoint ...` subcommand - [incidental] Factor multiple common uses of `FindFirstSymbolWithNameAndType(ConstString(".rs.info")` into static `IsRenderScriptScriptModule(ModuleSP module)` function, and replace original uses. llvm-svn: 283362
