[Lldb-commits] [lldb] [LLDB] Expose checking if the symbol file exists/is loaded via SBModule (PR #134163)

[Jacob Lalonde via lldb-commits]

https://github.com/Jlalond created https://github.com/llvm/llvm-project/pull/134163

The motivation for this patch is that in Statistics.cpp we [check to see if the module symfile is loaded](https://github.com/llvm/llvm-project/blob/990a086d9da0bc2fd53a6a4c95ecbbe23a297a83/lldb/source/Target/Statistics.cpp#L353C60-L353C75) to calculate how much debug info has been loaded. I have an external utility that only wants to look at the loaded debug info, which isn't exposed by the SBAPI.
