endings, since the file is supposed to have them, according to its
comments. Also set its svn:eol-style property. Noticed by Nico Weber.

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings.
There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

the "" and the suffix; that breaks names such as 'operator""if'. For symmetry,
also remove the space between the 'operator' and the '""'.

Our string literal parser copied any source-file new-line characters
into the execution string-literal. This is incorrect if the source-file
new-line character was a \r\n sequence because new-line characters are
merely \n.

-trigraphs is now an alias for -ftrigraphs. -fno-trigraphs makes it possible
to explicitly disable trigraphs, which couldn't be done before.
clang -std=c++11 -fno-trigraphs
now builds without GNU extensions, but with trigraphs disabled. Previously,
trigraphs were only disabled in GNU modes or with -std=c++1z.
Make the new -f flags the cc1 interface too. This requires changing -trigraphs
to -ftrigraphs in a few cc1 tests.
Related to PR21974.

extension. The GCC folks have decided to support this even though the standard
committee have not yet approved this feature.

Switch some warnings over to errors which should never have been warnings
in the first place. (Also, a minor fix to the preprocessor rules for
integer literals while I'm here.)

string literal needs cleaning (because it contains line-splicing in the
encoding prefix or in the ud-suffix), do not clean the section between the
double-quotes -- that's the "raw" bit!

basic source character set in C++98. Add -Wc++98-compat diagnostics for same in
literals in C++11. Extend such support to cover string literals as well as
character literals, and mark N2170 as done.
This seems too minor to warrant a release note to me. Let me know if you disagree.

starting with an underscore is ill-formed.
Since this rule rejects programs that were using <inttypes.h>'s macros, recover
from this error by treating the ud-suffix as a separate preprocessing-token,
with a DefaultError ExtWarn. The approach of treating such cases as two tokens
is under discussion for standardization, but is in any case a conforming
extension and allows existing codebases to keep building while the committee
makes up its mind.
Reword the warning on the definition of literal operators not starting with
underscores (which are, strangely, legal) to more explicitly state that such
operators can't be called by literals. Remove the special-case diagnostic for
hexfloats, since it was both triggering in the wrong cases and incorrect.

analysis to make the AST representation testable. They are represented by a
new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic
properties, including full CodeGen support, are achieved for free by this
representation.
UserDefinedLiterals can never be dependent, so no custom instantiation
behavior is required. They are mangled as if they were direct calls to the
underlying literal operator. This matches g++'s apparent behavior (but not its
actual mangling, which is broken for literal-operator-ids).
User-defined *string* literals are now fully-operational, but the semantic
analysis is quite hacky and needs more work. No other forms of user-defined
literal are created yet, but the AST support for them is present.
This patch committed after midnight because we had already hit the quota for
new kinds of literal yesterday.

collision between C99 hexfloats and C++0x user-defined literals by
giving C99 hexfloats precedence. Also, warning about user-defined
literals that conflict with hexfloats and those that have names that
are reserved by the implementation. Fixes <rdar://problem/9940194>.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
