Before this change, Clang uses the x86 representation for C++ method
pointers when generating code for PNaCl.  However, the resulting code
will assume that function pointers are 0 mod 2.  This assumption is
not safe for PNaCl, where function pointers could have any value
(especially in future sandboxing models).

So, switch to using the ARM representation for PNaCl code, which makes
no assumptions about the alignment of function pointers.

Since we're changing the "le32" target, this change also applies to
Emscripten.  The change is beneficial for Emscripten too.  Emscripten
has a workaround to make function pointers 0 mod 2.  This change would
allow the workaround to be removed.

Summary:
Add support for Adaptative matchers on the dynamic registry.
Each adaptative matcher is created with a function template. We instantiate the function N times, one for each possible From type and apply the techniques used on argument overloaded and polymorphic matchers to add them to the registry.

This is far from implementing all the rules given by
http://www.webkit.org/coding/coding-style.html

The important new feature is the support for styles that don't have a
column limit. For such styles, clang-format will (at the moment) simply
respect the input's formatting decisions within statements.

The 64-bit PowerPC ELF ABI requires a struct that contains a single
vector member to be passed in a vector register as though the wrapping
struct were not present.  Instead we were passing this as a byval
struct.

The same logic was already present for floating-point arguments, so
this patch just extends the logic to handle vector types.  The new
test case verifies that clang coerces the parameter and annotates it
as inreg.

Thanks,
Bill

function-like macro.  Clang will attempt to correct the arguments by detecting
braced initializer lists:

1) If possible, suggest parentheses around arguments
containing braced lists which will give the proper number of arguments.
2) If a braced list is detected at the start of a macro argument, it cannot be
corrected by parentheses.  Instead, just point out the location of these
braced lists.

This is still a fairly odd test. Clang wants to run gcc for assembling. At
least with -### it only prints that instead of actually trying to run it with
-ccc-echo.

These are cases where a scalar type is "destructed", usually due to
template instantiation (e.g. "obj.~T()", where 'T' is 'int'). This has
no actual effect and the analyzer should just skip over it.

The analyzer doesn't currently expect CFG blocks with terminators to be
empty, but this can happen when generating conditional destructors for
a complex logical expression, such as (a && (b || Temp{})). Moreover,
the branch conditions for these expressions are not persisted in the
state. Even for handling noreturn destructors this needs more work.

This reverts r186498.
