-When printing location avoid printing the filename if it is
same as the main file, not just if it has '.h' extension.
-Make sure we allocate enough bytes for storing as string a
huge line number.

This allows us to handle extreme cases of chained binary operators without causing stack
overflow.
The binary operators that are handled with the data recursive evaluator are
comma, logical, or operators that have operands with integral or enumeration type.

The functions memccpy, strdup, strndup, strlcat, and strlcpy should also have
object size checking support. Of course, this is only good if the C library also
supports these functions.

Err on the side of brevity and rename (while providing aliases for the original
name) -Wbool-conversions, -Wint-conversions, and -Wvector-conversions for
consistency with constant, literal, string, and sign conversion warnings. And
name the diagnostic groups explicitly while I'm here rather than rewriting the
string in the groups and sema td files.
Curiously, vector-conversion is not under -Wconversion. Perhaps it should be.

breaking bootstrap. No test yet: it's quite hard to tickle the failure case.
The specific testcase for this wouldn't be useful for testing anything more
general than a reintroduction of this precise bug in any case.

Original commit message:
Provide -Wnull-conversion separately from -Wconversion.
Like GCC, provide a NULL conversion to non-pointer conversion as a separate
flag, on by default. GCC's flag is "conversion-null" which we provide for
cross compatibility, but in the interests of consistency (with
-Wint-conversion, -Wbool-conversion, etc) the canonical Clang flag is called
-Wnull-conversion.
Patch by Lubos Lunak.
Review feedback by myself, Chandler Carruth, and Chad Rosier.

locations for diagnostics we're not going to emit, and don't track the subobject
designator outside C++11 (since we're not going to use it anyway).
This seems to give about a 0.5% speedup on 403.gcc/combine.c, but the results
were sufficiently noisy that I can't reject the null hypothesis.

-fno-inline-functions.
This behaves much like -fno-inline in gcc, but based on a discussion with
Daniel it was decided that -fno-inline-functions should subsume -fno-inline.
Please speak up if you object. The -fno-inline flag remains ignored.

scoped enumeration members. Later uses of an enumeration temploid as a nested
name specifier should cause its instantiation. Plus some groundwork for
explicit specialization of member enumerations of class templates.

- This may seem superflous, but actually this allows the optimizer to more
easily eliminate the isActive() checks needed by the SemaDiagnosticBuilder
and DiagnosticBuilder dtors. And by more easily, I mean the current LLVM is
actually able to do one and not the other. :)
This is good for another 20k code size reduction.

- As with DiagnosticBuilder, it is very important that SemaDiagnosticBuilder be
completely inline to ensure that the compiler can rip it apart and sink it to
registers.
This is good for another 30k reduction in code size.

function templates as well.
A future commit will mangle the added name with the template args
like classes are mangled.
