Convert IdentifierInfo's to be printed the same as DeclarationNames
with implicit quotes around them. This has a bunch of follow-on
effects and requires tweaking to a whole lot of code. This causes
a regression in two tests (xfailed) by causing it to emit things like:
Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')
instead of:
Line 10: duplicate interface declaration for category 'MyClass1(Category1)'
I will fix this in a follow-up commit.
As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency. This is good, but I was planning to do this
as an independent patch. There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

add support for inserting a DeclarationName into a diagnostic directly

Add support for sending QualType's directly into diags and convert two

them for uniformity and future extension.
Doing this requires a little function pointer dance to prevent libbasic

New AST node to access "implicit" setter/getter using property dor syntax.

Fix a weird inconsistency with hex floats. Previously the lexer
would not eat the "-1" in "0x0p-1", but LiteralSupport would accept
it when extensions are on. This caused strangeness and failures
when hexfloats were properly treated as an extension (not error)
in LiteralSupport.

remove the NumericLiteralParser::Diag helper method, inlining it into
its call sites. This makes it more explicit when the hasError flag is

PP.Diag and Diag in this code.

Move the Preprocessor::Diag methods inline. This has the interesting
(and carefully calculated) effect of allowing the compiler to reason
about the aliasing properties of DiagnosticBuilder object better,
allowing the whole thing to be promoted to registers instead of
resulting in a ton of stack traffic.
While I'm not very concerned about the performance of the Diag() method
invocations, I *am* more concerned about their code size and impact on the
non-diagnostic code. This patch shrinks the clang executable (in
release-asserts mode with gcc-4.2) from 14523980 to 14519816 bytes. This
isn't much, but it shrinks the lexer from 38192 to 37776, PPDirectives.o

Change the Lexer::Diag method to not magically silence warnings,

Add the concept of "modifiers" to the clang diagnostic format
strings. This allows us to have considerable flexibility in how
these things are displayed and provides extra information that
allows us to merge away diagnostics that are very similar.
Diagnostic modifiers are a string of characters with the regex
[-a-z]+ that occur between the % and digit. They may
optionally have an argument that can parameterize them.
For now, I've added two example modifiers. One is a very useful
tool that allows you to factor commonality across diagnostics
that need single words or phrases combined. Basically you can
use %select{a|b|c}4 with with an integer argument that selects
either a/b/c based on an integer value in the range [0..3).
The second modifier is also an integer modifier, aimed to help
English diagnostics handle plurality. "%s3" prints to 's' if
integer argument #3 is not 1, otherwise it prints to nothing.
I'm fully aware that 's' is an English concept and doesn't
apply to all situations (mouse vs mice). However, this is very
useful and we can add other crazy modifiers once we add support
for polish! ;-)
I converted a couple C++ diagnostics over to use this as an
example, I'd appreciate it if others could merge the other
likely candiates. If you have other modifiers that you want,
lets talk on cfe-dev.

move the diagnostic location and ID out of DiagnosticInfo and store it in
the Diagnostic class. Since we can already only have one diagnostic in
flight at a time, this shrinks DiagnosticInfo.
This reduces DiagnosticInfo to being basically a rather crazy smart pointer
to a DiagnosticInfo :)

move diagnostic insertion methods to be free methods instead of

Change -verify mode to find the "expected-error" and "expected-warning" strings

#include'd headers for expected-error/warning strings, and it also means that it
