Turn CLANG_ENABLE_{ARCMT,REWRITER,STATIC_ANALYZER} into proper options so that
users can disable those. Just like in autoconf generated makefiles.

Split off casts to void* for -Wint-to-pointer-cast to subgroup -Wint-to-void-pointer-cast.

This change is motivated from user feedback that some APIs use
void* as an opaque "context" object that may not really be a pointer.
Such users want an ability to turn off the warning for casts
to void* while preserving the warning for other cases.

Implements <rdar://problem/14016721>.

Fixes error when splitting block comments.

When trying to fall back to search from the end onwards, we
would still find leading whitespace if the leading whitespace
went on after the end of the line.

[libclang] When indexing a @synthesize, don't consider that it defines a getter/setter if one is already defined by the user.

Fixes rdar://13925258

[analyzer; new edges] In for(;;), use the ForStmt itself for loop notes.

Most loop notes (like "entering loop body") are attached to the condition
expression guarding a loop or its equivalent. For loops may not have a
condition expression, though. Rather than crashing, just use the entire
ForStmt as the location. This is probably the best we can do.

Add support to fallback on operator new when a placement operator new[] is called for which there is no valid declaration.  This fallback only happens in Microsoft compatibility mode.  This patch addresses PR13164, and improves support for the WDK.

Switching the tests to use size_t instead of unsigned int to hopefully appease the Linux x64 build bot.

Fix default value of clang-format-diff's -p option.

This way, it has the same default as 'patch' and also the example in the
code makes more sense as it is explicitly setting -p 1.

Microsoft has a language extension which allows union members to be
references.  What's more, they use this language extension in their
ATL header files (which come as part of MFC and the Win32 SDK).  This patch implements support for the Microsoft extension, and addresses PR13737.
