Bug #49829 Many "hides virtual function" warnings with

SunStudio
      
SunStudio compilers of late warn about methods that might hide
methods in base classes due to the use of overloading combined
with overriding. SunStudio also warns about variables defined
in local socpe or method arguments that have the same name as
a member attribute of the class.
      
This patch renames methods that might hide base class methods,
to make it easier both for humans and compilers to see what is
actually called. It also renames variables in local scope.


sql/field.cc:
  Local scope variable or method argument same as class 
  attribute.
sql/item_cmpfunc.cc:
  Local scope variable or method argument same as class 
  attribute.
