Summary:
-regex and -iregex both mimic options of the find utility.
Made the default list of extensions case-insensitive, so that it's not only C
and CPP extensions are accepted in upper case.

ASTContext: Declare builtin types implicitly
__builtin_va_list and friends have been showing up where they shouldn't for way
to long, making unwanted appearences in -ast-print, tooling and source level
visitors and even the hello world tutorial on the clang website.
This commit factors down the implicit typedef and record creation facilities to
ensure they're marked implicit.
Also fixes a unit test that was testing incorrect behaviour, and removes old
hacks in the DeclPrinter that tried to skip implicit declarations manually.

Quick-Fix pointer arithmetic when performing multi-D new-array initialization.
clang still doesn't emit the right llvm code when initializing multi-D arrays it seems.
For e.g. the following code would still crash for me on Windows 7, 64 bit:
auto f4 = new int[100][200][300]{{{1,2,3}, {4, 5, 6}}, {{10, 20, 30}}};
It seems that the final new loop that iterates through each outermost array and memsets it to zero gets confused with its final ptr arithmetic.
This patch ensures that it converts the pointer to the allocated type (int [200][300]) before incrementing it (instead of using the base type: 'int').
Richard somewhat squeamishly approved the patch (as a quick fix to potentially make it into 3.4) - while exhorting for a more optimized fix in the future. http://llvm-reviews.chandlerc.com/D2398

Tighten test regexes checking for __attribute__((thiscall)) on function types.
The tests were perhaps made too relaxed in r197164 when we switched to the new

We should still look into whether we should print these attributes at all in
these cases.
Objective-C. Do not issue warning when 'readonly'

extension override, memory management attribute is
needed to produce correct Code Gen. for the
property getter in any case and this warning becomes
confusing to user. // rdar://15641300

Well, that's one way to pass a test, I suppose. Unfortunately actually doing

Unify type trait parsing
Type trait parsing is all over the place at the moment with unary, binary and
n-ary C++11 type traits that were developed independently at different points
in clang's history.
There's no good reason to handle them separately -- there are three parsers,
three AST nodes and lots of duplicated handling code with slightly different
implementations and diags for each kind.
This commit unifies parsing of type traits and sets the stage for further
consolidation.
No change in behaviour other than more consistent error recovery.

Change semantics of regex expectations in the diagnostic verifier
Previously, a line like
// expected-error-re {{foo}}
treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".
This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.
(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

[objcmt] When emitting a remap file, use a json format with the edit entries, instead of applying the changes
to a temp file directly.
This allows to combine the edits when they can be different based on whether you saw
the implementation or not, e.g. with the designated initializer migration.
[objcmt] When whitelisting the headers we want to modify, allow changing the
the ObjC implementation declarations, just don't change implementations for
classes that are not in the whitelisted headers.
For example, if we change a method to return 'instancetype' we should also
update the method definition in the implementation.
