0f2a3607e0 Keep track of all of the import declarations that are parsed or
implicitly generated in a translation unit. Modules will need this
information to identify the actual imports that occurred.

bcfc7d0229 When we treat an #include or #import as a module import, create an
implicit ImportDecl in the translation unit to record the presence of
the import.

dac7f9a57e Only perform checking of the predefines buffer when loading a
precompiled header. Previously, we were trying to gather predefines
buffers from all kinds of AST files (which doesn't make sense) and
were performing some validation when AST files were loaded as main
files. 

With these tweaks, using PCH files that import modules no longer fails
immediately (due to mismatched predefines buffers). However, module
visibility is lost, so this feature does not yet work.

d572f82e49 Fix wrong-code bug when a const automatic variable of struct type has both a
mutable member and a constant initializer. We'd previously promoted such
variables to global constants, resulting in nasal demons if the mutable member
was modified.

This is only a temporary fix. The subtle interplay between isConstantInitializer
and CGExprConstant is very bug-prone; there are some other issues in this area
which I will be addressing in subsequent, more major reworking of this code.

ff2be53f8f Introduce the notion of name visibility into modules. For a given
(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).

This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).

are no longer needed (most files only needed the Module type).
