Stephen Kelly b22e5d0ab7 Remove some obsolete declarations
Ensure that cmStandardIncludes.h is included before any platform header
in cmGeneratorExpressionEvaluator.h.  That file needs to change as
a result of removal of the cmMakefile.h header from
cmGeneratorExpressionNode.h, affecting the compilation of
cmGeneratorExpressionNode.cxx.

On AIX we need to include our own headers first to get large file
support macros defined consistently within system headers.  The old
order in this header worked only because it was always included after
other headers.

Stephen Kelly b80557c7bd file(GENERATE): Evaluate early to allow generating source files
The evaluation files must be known before cmTargetTraceDependencies
attempts to find them, but we must actually generate the files after
cmTargetTraceDependencies, as that can add to target SOURCES.  The
limitation is that the generated output name must not depend on the
SOURCES of a target if the generated file is used by that target.

Mark the output files as GENERATED so that trace dependencies does
not expect them to already exist in the filesystem.

Move the invokation of ForceLinkerLanguage in the Generate logic
to after the generated file names are known.  ForceLinkerLanguage
tries to determine the sources of a target (in order to determine
an already-known language) and otherwise fails to get information
about the generated file.

Test that the output of file(GENERATE) can be used as a target source
file and that accessing the target SOURCES in the name of the output
file is an error.  Accessing the TARGET_OBJECTS would be a similar
error if it was legal to use that generator expression in this
context.  That is not currently possible and is a different error
condition, so test the current error output as a reminder to change
the expected output if that becomes possible in the future.  Test
that generated rule files resulting from cmTargetTraceDependencies
appear in the SOURCES generated in the output file.

Stephen Kelly 0dfe395e3c Features: Add COMPILE_FEATURES generator expression.
Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.

Stephen Kelly 5de63265e3 Genex: Only evaluate TARGET_OBJECTS to determine target sources.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc.  To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.

This commit may be reverted in the future if a solution to the
above difference is implemented.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Stephen Kelly c4373b33b2 cmTarget: Make GetProperty() const.
This has follow-on effects for other methods and classes. Further
work on making the use of const cmTarget pointers common can be
done, particularly with a view to generate-time methods.

Stephen Kelly f2ab17d4db Keep track of all targets seen while evaluating a genex.
As dependencies of the generator expression, these will re-exported
in try_compile generated code.

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.

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:

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/3615/focus=5170
 (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.
