The PolicyPushPop constructor arguments and Quiet method were used to
pass non-default arguments to PushPolicy and PopSnapshot, but no clients
use them anymore.
The `PopPolicyBarrier` method is actually responsible for closing any
scope opened by creating a snapshot. Rename it to `PopSnapshot` and add
a comment explaining the purpose of the poilcy-scope-specific part of
the method.
Commit v3.4.0-rc1~494^2~4 (cmMakefile: Add API for elseif to create
backtrace., 2015-05-29) removed the use of cmMakefileCall to push/pop
execution context in favor of a new way to create backtraces.
However, a call to cmMakefile::GetExecutionContext is still invoked to
issue a contextual CMP0054 warning through cmConditionEvaluator. As
the elseif is not part of the call stack, this resulted in trying to
access an empty vector.
Avoid the attempt at getting execution context when evaluating elseif by
constructing a context and backtrace on behalf of the cmConditionEvaluator
in all cases.
