A Clang configuration when importing C++ modules.
This class computes a list of include paths and module names that can be imported given a list of source files. Currently only used when importing the 'std' module and its dependencies.

Creates a configuration by analyzing the given list of used source files.
The triple (if valid) is used to search for target-specific include paths.

Creates an empty and invalid configuration.

private |
Analyze a given source file to build the current configuration.
Returns false iff there was a fatal error that makes analyzing any further files pointless as the configuration is now invalid.
