ARM Cost Model:  We need to detect the max bitwidth of types in the loop in order to select the max vectorization factor.
We don't have a detailed analysis on which values are vectorized and which stay scalars in the vectorized loop so we use
another method. We look at reduction variables, loads and stores, which are the only ways to get information in and out
of loop iterations. If the data types are extended and truncated then the cost model will catch the cost of the vector
zext/sext/trunc operations.

Revert r172153, "llvm/lib/MC/MCParser/AsmParser.cpp: [ms-inline-asm] Fix a couple of undefined behaviors. Operand->needAddressOf() is not initialized at !Operand->isReg()."

It has been redundant since r172157.

Making a data formatter for wchar_t *

Right now, only OS X has a way to determine the column width of a string
(PR14910). Until we have a good way to deal with this, we just won't
print carets, source ranges, or fixits for SMDiagnostic if the source line
has multibyte characters in it.

llvm-svn: 172164

It's better to show no caret/ranges/fixits than to show them misaligned.
(It scares me a bit that Clang is going to show them misaligned on
systems without a proper llvm::sys::locale::columnWidth.) See PR14910.

This reverts commit a03cc72bedd015b7eb76e9ac650992f58a48549d.

Before we learned about :doc:, we used :ref: and put a dummy link at the
top of each page. Don't do that anymore.

This fixes PR14891 as a special case.

To ensure that custom assertions/conditional would also be supported,
just check if the ivar that needs to be invalidated or set to nil is
compared against 0.

Unfortunately, this will not work for code containing 'assert(IvarName)'

Objective-C method declarations look like this:

- (returntype)name:(type)argname anothername:(type)arg2name;

In google style, there's no space after the leading '-' but one after
"(returntype)" instead (but none after the argument types), see
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Method_Declarations_and_Definitions

Not inserting the space after '-' is easy, but to insert the space after the
return type, the formatter needs to know that a closing parenthesis ends the
return type. To do this, I tweaked the code in parse() to check for this, which
in turn required moving detection of TT_ObjCMethodSpecifier from annotate() to
parse(), because parse() runs before annotate().

(To keep things interesting, the return type is optional, but it's almost
always there in practice.)

This change is basically just copying changes that we've used for Apple's
clang builds to the script used for building llvmCore. Besides cleaning it
up to use xcrun to locate the proper versions of tools, especially for cross
compiling, it fixes the build to work with newer versions of clang that
honor SDKROOT settings in the environment.

In some cases, we just pick any ivar that needs invalidation and attach
the warning to it. Picking the first from DenseMap of pointer keys was
triggering non-deterministic output.
