Richard Smith acd4d3d52a -Wc++98-compat warnings for the lexer. 
This also adds a -Wc++98-compat-pedantic for warning on constructs which would
be diagnosed by -std=c++98 -pedantic (that is, it warns even on C++11 features
which we enable by default, with no warning, in C++98 mode).

Jeffrey Yasskin a722170eb9 Implement the first piece of a -Wc++98-compat flag so that people can build in 
C++11 mode but keep their sources compatible with C++98.  This patch implements
the -Wc++98-compat-variadic-templates sub-flag and -Wc++98-compat to include
it.
