It is an old function that does a lot more than required by
CalcSpillWeights, which was the only remaining caller.
The isRematerializable() function never actually sets the isLoad
argument, so don't try to compute that.

Within the guts of CheckFormatHandler, the IsObjCLiteral flag was being used in
two ways: to see if null bytes were allowed, and to see if the '%@' specifier
is allowed.* The former usage has been changed to an explicit test and the
latter pushed down to CheckPrintfHandler and renamed ObjCContext, since it
applies to CFStrings as well.
* This also changes how wide chars are interpreted; in OS X Foundation, the
wide character type is 'unichar', a typedef for short, rather than wchar_t.

Refactorings of watchpoint creation APIs so that SBTarget::WatchAddress(), SBValue::Watch(), and SBValue::WatchPointee()
now take an additional 'SBError &error' parameter (at the end) to contain the reason if there is some failure in the
operation. Update 'watchpoint set variable/expression' commands to take advantage of that.
Update existing test cases to reflect the API change and add test cases to verify that the SBError mechanism works for
SBTarget::WatchAddress() by passing an invalid watch_size.

replacement to make it at least as generic as the instruction being replaced.
This includes:
* dropping nsw/nuw flags
* getting the least restrictive tbaa and fpmath metadata
* merging ranges
Fixes PR12979.

that automatically generated setters/getters only
get added to a class after explicitly declared (or
synthesized) getters/setters had the chance to be
added. This eliminates conflicts creating errors
of the form:
error: instance method '...' has incompatible result
types in different translation units ('X *' vs. 'id')

temporary or an array subobject of a class temporary, and the resulting value
is used to initialize a pointer which outlives the temporary. Such a pointer
is always left dangling after the initialization completes and the array's
lifetime ends.
In order to detect this situation, this change also adds an
LValueClassification of LV_ArrayTemporary for temporaries of array type which
aren't subobjects of class temporaries. These occur in C++11 T{...} and GNU C++
(T){...} expressions, when T is an array type. Previously we treated the former
as a generic prvalue and the latter as a class temporary.
