Rework InitPreprocessor to use a MacroBuilder class instead of pushing around
std::vectors.

- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

Extend -remap-file=from;to to permit mapping from a non-existent

Extend -remap-file=from;to to permit mapping from a non-existent
file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

Move file-remapping logic into InitPreprocesor. No functionality change

Exit the command line into <built-in> instead of going directly from the command line to the input file.

We passed <built-in> on the way in, so we should pass it again on the way out.
