[Lldb-commits] [lldb] [lldb] Test global variable support of dwim-print (NFC) (PR #157908)

[Dave Lee via lldb-commits]

https://github.com/kastiglione created https://github.com/llvm/llvm-project/pull/157908

DIL has made frame variable support global variables, which in turn means dwim-print
inherits support for global variables.
