  [Lex] Consider a PCH header-guarded even with #endif truncated

This seems to be a more useful behavior for tools that use preambles.
I believe it doesn't affect real compiles: the PCH is only included once
when used, and recursive inclusion of the main-file *within* the PCH
isn't supported in any case.
