[cfe-dev] Adding a framework to a CompilerInvocation

[Alex L via cfe-dev]

Hi Felix,

The framework search path options (that correspond to -F) are stored in an
instance of the HeaderSearchOptions class inside the CompilerInvocationBase
class, and you can add an new -F search path using the AddPath method.

I think you can still use the memory buffer as source even if you create
the invocation using command line arguments if you remap the buffer to the
filename after creating the invocation (addRemappedFile in
PreprocessorOptions).
