With -style=file, clang-format now starts to search for a .clang-format
file starting at the file given with -assume-filename if it reads from
stdin. Otherwise, it would start searching from the current directory,
which is not helpful for editor integrations.

Also changed vim, emacs and sublime integrations to actually make use of
this flag.

This fixes llvm.org/PR17072.

The code in CGExpr was added back in 2012 (r165536) but not exercised in tests
until recently.

Detected on the MemorySanitizer bootstrap bot.

Dotfiles are impractical on Windows. This makes clang-format search
for the style configuration file as '_clang-format' in addition to
the usual '.clang-format'. This is similar to how VIM searches for
'_vimrc' on Windows.

fallback syntax used when we fail to find a '.clang-format' file. Adjust
variable names appropriately.

Update the editor integration pieces that specify a '-style' option to
specify it as '-style=file'. I left the functionality in place because
even if the preferred method is to use '.clang-format' files, this way
if someone needs to clobber the style in their editor we show how to do
so in these examples.

Also check in a '.clang-format' file for Clang to ensure that separate
checkouts and builds of Clang from LLVM can still get the nice
formatting. =] This unfortunately required nuking the test for the
absence of a '.clang-format' file as now the directory happening to be
under your clang source tree will cause there to always be a file. ;]

Based on a patch by Benno Rice!

Move individual group name strings from the OptionTable into one big char array. Then only store offsets into it in the OptionTable. Saves about 4K from the clang binary and removes 400 relocation entries from DiagnosticIDs.o.

llvm-svn: 189568

llvm-svn: 189445

The individual group and subgroups tables are now two large tables. The option table stores an index into these two tables instead of pointers. This reduces the size of the options tabe since it doesn't need to store pointers. It also reduces the number of relocations needed.

My build shows this reducing DiagnosticsIDs.o and the clang binary by ~20.5K. It also removes ~400 relocation entries from DiagnosticIDs.o.

Summary:
Makes functions with implicit calling convention compatible with
function types with a matching explicit calling convention.  This fixes
things like calls to qsort(), which has an explicit __cdecl attribute on
the comparator in Windows headers.

Clang will now infer the calling convention from the declarator.  There
are two cases when the CC must be adjusted during redeclaration:
1. When defining a non-inline static method.
2. When redeclaring a function with an implicit or mismatched
convention.

Fixes PR13457, and allows clang to compile CommandLine.cpp for the
Microsoft C++ ABI.

Excellent test cases provided by Alexander Zinenko!

This reverts commit r189371, it broke the in-source cmake build.

Variables set in a makefile are not overridden by environment variables.
Make sure we actually override CC and CXX when using scan-build.

Symlinks to clang should go in Clang's build directory, not LLVM's.

Thanks for pointing this out, Stephen. I think this is right now -- I
attempted to try all four valid combinations with both the autoconf and
CMake builds.

Basically, isInMainFile considers line markers, and isWrittenInMainFile
doesn't.  Distinguishing between the two is useful when dealing with
files which are preprocessed files or rewritten with -frewrite-includes
(so we don't, for example, print useless warnings).
