This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
In commit 74de9a73 (cmGlobalGenerator: Delegate storage of enabled
languages to cmState, 2015-04-11) the original LanguageEnabled
member of cmGlobalGenerator was left behind by mistake. One use
of it in EnableLanguagesFromGenerator (for try_compile) was left,
but the member is not populated anymore. Drop the member and
teach EnableLanguagesFromGenerator to copy the list of enabled
languages from one cmState to the other.

The purpose of the stack is to allow access only to the top of it. Access
to items which are not at the top is needed, so cmDefinitions objects
get a Parent pointer.
The existence of the Parent pointer is a workaround for the inappropriate
use of stack in the first place. Remove it now.
Construct the final list directly in a named return value. Use
a single set to track bindings already found.
