A value number is a PHI def if and only if it begins at a block
boundary. This can be derived from the def slot, a separate flag is not
necessary.

This option replaces the existing live interval computation with one
based on LiveRangeCalc.cpp. The new algorithm does not depend on
LiveVariables, and it can be run at any time, before or after leaving
SSA form.

sel_getName() calls are generated for all Objective-C
selectors before static literals are moved to the

Clang's -Wformat fix-its currently suggest using "%zu" for values of
type size_t (in C99 or C++11 mode). However, for a type such as
std::vector<T>::size_type, it does not notice that type is actually
typedeffed to size_t, and instead suggests a format for the underlying
type, such as "%lu" or "%u".

This commit makes the format string fix mechanism walk the typedef chain
so that it notices if the type is size_t, even if that isn't "at the
top".

Also, fix a subtle bug, which occurred due to lookupPrivateMethod
defined in DeclObjC.h not looking up the method inside parent's
categories.

Note, the code assumes that Class's parent object has the same methods
as what's in the Root class of a the hierarchy, which is a heuristic
that might not hold for hierarchies which do not descend from NSObject.
Would be great to fix this in the future.

The __BYTE_ORDER__ predefined macro was added in GCC 4.6:
http://gcc.gnu.org/onlinedocs/gcc-4.6.0/cpp/Common-Predefined-Macros.html

It's used like the following:

 #if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__
 ...
 #elif __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__
 ...
 #else
 #error insane architecture like the pdp-11
 #endif

There's a similar macro, __FLOAT_WORD_ORDER__, but it looks like it
mainly exist to accommodate fairly obscure architectures and ARM's
old FPA instructions, so it doesn't seem nearly as useful.

The tests are updated to check for the correct(at least, based on
clang's current output) value of the macro on each target. So now the
suite will catch bugs like the one fixed in r157626.

Fix PR13394: Erasing from a vector changes the end of the vector, so make sure we always have the right end.

llvm-svn: 160855

The rationale here is that it's hard to write loops containing vector erases and
it only shows up if the vector contains non-trivial objects leading to crashes
when forming them out of garbage memory.
