Stephen Kelly e48d84209c Cache context-independent includes on evaluation.
Generator expressions whose output depends on the configuration
now record that fact. The GetIncludeDirectories method can use
that result to cache the include directories for later calls.

GetIncludeDirectories is called multiple times for a target
for each configuration, so this should restore performance for
multi-config generators.

Stephen Kelly bf5ece51c3 Keep track of properties used to determine linker libraries.
Those properties can't later be implicitly defined by the interface
of those link libraries.

Stephen Kelly 26def1771d Make all relevant targets available in the genex context.
The current node being evaluated transitively in the generator
expression must be available to resolve mapped configs.

Stephen Kelly d8a59ea4b3 Port cmGeneratorExpression to cmTarget from cmGeneratorTarget.
Following from the discussion here:

 (Re: Generator expressisons in target properties, 26 Oct 12:10)

we can't split cmTarget API for linking into cmGeneratorTarget. In
the future we will probably also need to move the include and compile
definitions API back to cmTarget so that it can be used by export().

Stephen Kelly 7e807472d2 Add API to check that dependent target properties form a DAG.
Initially this will only be used to check for self-references, but
can be extended to check for cycles when chaining properties of other
targets.

Stephen Kelly 239ac84153 Add a generator expression for target properties.
There are two overloads, so that it can use the operational
target when a target property is being evaluated, and a target
can alternatively be specified by name.

At this point, the generators don't chain. That comes later.

Stephen Kelly f1eacf0e07 cmGeneratorExpression: Re-write for multi-stage evaluation
The expressions may be parsed and then cached and evaluated multiple
times.  They are evaluated lazily so that literals such as ',' can be
treated as universal parameter separators, and can be processed from
results without appearing literally, and without interfering with the
parsing/evaluation of the entire expression.
