Chris Lattner 794c001ad4 fix PR3764 - A redefinition of a pre-processor macro fails
Redefinition checking should ignore the leading whitespace and
start of line flags on the first token of an expansion.

Chris Lattner 2edf0fcb75 fix PR3579: __LINE__ expands to the presumed location of the
*end* of a macro instantiation, not the start of it.  This is
really all about bug-for-bug compatibility with GCC, but not
doing this breaks the FreeBSD kernel.

Chris Lattner 9dc9c206d3 track "just a little more" location information for macro instantiations.
Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced.  For object-like macros, this doesn't
change anything.  For _Pragma and function-like macros, this means we track
the locations of the ')'.

This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

Mike Stump 6b63074de9 Fix limits.h for linux, as glibc does a #include_next unless
_GCC_LIMITS_H_ is defined, when __GNUC__ is defined.

Also, we need to stay away from possible conflicts with header guards.
We should use CLANG_ to prefix all header guards.

Chris Lattner 1c967784f3 Implement handling of file entry/exit notifications from GNU
line markers, including maintenance of the virtual include stack.

For something like this:

# 42 "bar.c" 1
# 142 "bar2.c" 1

#warning zappa
# 92 "bar.c" 2
#warning gonzo
# 102 "foo.c" 2
#warning bonkta


we now produce these three warnings:

#1:
In file included from foo.c:3:
In file included from bar.c:42:
bar2.c:143:2: warning: #warning zappa
#warning zappa
 ^

#2:

Chris Lattner f1ca7d3e02 Introduce a new PresumedLoc class to represent the concept of a location
as reported to the user and as manipulated by #line.  This is what __FILE__,
__INCLUDE_LEVEL__, diagnostics and other things should follow (but not 
dependency generation!).  

This patch also includes several cleanups along the way: 

- SourceLocation now has a dump method, and several other places 
  that did similar things now use it.
- I cleaned up some code in AnalysisConsumer, but it should probably be
  simplified further now that NamedDecl is better.
- TextDiagnosticPrinter is now simplified and cleaned up a bit.

This patch is a prerequisite for #line, but does not actually provide 
any #line functionality.

Chris Lattner a7e2e74cef Avoid testing / ## * in the lexer. This will cause an unhelpful error message
to be emitted from the lexer.  This fixes macro_paste_c_block_comment.c

Chris Lattner 30a2fa14ae 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.
