[PATCH v14 0/2] add annotation in 'info locals' command for variables shadowing case

[Abdul Basit Ijaz <abdul.b.ijaz@intel.com>]

Hi All,

For the variable shadowing case, these patches add the annotation "shadowed"
and location information to the shadowed variables so that it is easier for
the end user to identify which variable was shadowed.

Patch #1 updates "info locals" command
Path #2 is for the mi commands '-stack-list-locals' and '-stack-list-variables'.
