Before this change, the program:
  int var;
  int main(void) { return 0; }
when run under 'nm -g' would show 'U var' with the gold plugin and
'B var' with gcc.

when I was looking at functions used by python.

Highlights include, better largefile support (64-bit file sizes on 32-bit
systems), fputs string is nocapture, popen/pclose added (popen being noalias
return), modf and frexp and friends. Also added some missing 'break' statements
and combined identical sections.

DiagnoseUseOfDeprecatedDecl method.  This ensures that they
are treated consistently.  This gets us 'unavailable' support
on a few new types of decls, and makes sure we consistently
silence deprecated when the caller is also deprecated.

as well as its identifier.

*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.

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.

Fix pr3571: If stride is a value defined by an instruction, make sure it dominates the loop preheader. When IV users are strength reduced, the stride is inserted into the preheader. It could create a use before def situation.

late binding of newly synthesize ivars (when we support it).
