Change Preprocessor::ReadFunctionLikeMacroArgs to use a SmallVector to lex
...
argument tokens into instead of a real vector. This avoids some malloc
traffic in common cases. In an "abusive macro expansion" testcase, this
reduced -Eonly time by 25%.

Change MacroArgs to allocate space for the unexpanded tokens immediately after

so shortly.

speed up a brutal macro-expansion torture test by about 30% (1.5 -> 1.0s)

Simplify "raw lexing mode" even further. Now the preprocessor is only called

into when a hard error is found. This simplifies logic and eliminates the need
for the preprocessor to know about raw mode.

Move LexingRawMode handling of file EOF out of the preprocessor into the
...
lexer. This makes more logical sense and also unbreaks the case when the
lexer hasn't been pushed onto the PP include stack. This is the case when
pasting identifiers. This patch implements macro_paste_bcpl_comment.c.

Change Preprocessor::SkippingContents into Lexer::LexingRawMode. Raw mode
...
is an intra-lexer property, not a inter-lexer property, so it makes sense
for it to be define here. It also makes no sense for macros, and allows us
to define it more carefully in the header.
While I'm at it, improve comments and structuring in Lexer.h
