- This just scratches the surface, We have pretty horrible test coverage in
this area it seems like, but this at least covers the change in r173410.

This combines two small changes:
1) Put a penalty on breaking after "<"
2) Only produce a hanging indent when parameters are separated by
commas.
Before:
aaaaaaaaaaaaaaaaaaaaaaaa<
aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa>(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
aaaaaa(new Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaa));
After:
aaaaaaaaaaaaaaaaaaaaaaaa<aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa>(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
aaaaaa(new Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaa));
This changes one ObjC test, but AFAICT this is not according to any
style guide (neither before nor after). We probably should be aligning
on the ":" there according to:

Otherwise, really long nested name specifiers can easily lead to a
violation of the column limit.
Not sure about the rules for indentation in those cases, so input is
appreciated (see tests.).

with -target i686-win32, you will see;
debug-info-static-member.cpp:11:22: error: in-class initializer for static data member of type 'const float' requires 'constexpr' specifier [-Wstatic-float-init]
const static float const_b = 3.14;

and split it out of -Wgnu into its own warning flag.
* In C++11, this is now a hard error (GCC has no extension here in C++11 mode).
The error can be disabled with -Wno-static-float-init, and has a fixit to
add 'constexpr'.
* In C++98, this is still an ExtWarn, but is now controlled by
-Wstatic-float-init as well as -Wgnu.

AST reader.
The global module index tracks all of the identifiers known to a set
of module files. Lookup of those identifiers looks first in the global
module index, which returns the set of module files in which that
identifier can be found. The AST reader only needs to look into those
module files and any module files not known to the global index (e.g.,
because they were (re)built after the global index), reducing the
number of on-disk hash tables to visit. For an example source I'm
looking at, we go from 237844 total identifier lookups into on-disk
hash tables down to 126817.
Unfortunately, this does not translate into a performance advantage.
At best, it's a wash once the global module index has been built, but
that's ignore the cost of building the global module index (which
is itself fairly large). Profiles show that the global module index
code is far less efficient than it should be; optimizing it might give
enough of an advantage to justify its continued inclusion.

for template instantiations, and use it to simplify the implementation of
FunctionDecl::isInlined().
This incidentally changes the result of isInlined on a declared-but-not-defined
non-inline member function from true to false. This is sort of a bug fix, but
currently isInlined is only called on function definitions, so it has no visible
effects.

The idea is to introduce a higher level "user mode" option for
different use scenarios. For example, if one wants to run the analyzer
for a small project each time the code is built, they would use
the "shallow" mode.
The user mode option will influence the default settings for the
lower-level analyzer options. For now, this just influences the ipa
modes, but we plan to find more optimal settings for them.
llvm-svn: 173386
The idea is to eventually place all analyzer options under
"analyzer-config". In addition, this lays the ground for introduction of
a high-level analyzer mode option, which will influence the
default setting for IPAMode.

SATestBuild expects to compare output directories for each invocation of
scan-build that it runs, but scan-build clears out empty directories by
default. We were coincidentally not getting that behavior until r173294.

This is a missing piece for C99 conformance.
This patch handles UCNs by adding a '\\' case to LexTokenInternal and
LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN.
If the UCN is not syntactically well-formed, we fall back to the old
treatment: a backslash followed by an identifier beginning with 'u' (or 'U').
Because the spelling of an identifier with UCNs still has the UCN in it, we
need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo.
Of course, valid code that does *not* use UCNs will see only a very minimal
performance hit (checks after each identifier for non-ASCII characters,
checks when converting raw_identifiers to identifiers that they do not
contain UCNs, and checks when getting the spelling of an identifier that it
does not contain a UCN).
This patch also adds basic support for actual UTF-8 in the source. This is
treated almost exactly the same as UCNs except that we consider stray
Unicode characters to be mistakes and offer a fixit to remove them.
