variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!

I have run these tests under many configurations on the exact same OS as
the failures, and I can't reproduce them :(.

directory_iterator preserve InputIterator semantics on copy.

Add support for vectors of pointers.

was returning incorrect values in rare cases, and incorrectly marking
exact conversions as inexact in some more common cases. Fixes PR11406, and a
missed optimization in test/CodeGen/X86/fp-stack-O0.ll.

These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!

Add a test case for the edge case that triggers this. Thanks to Chandler for bringing this to my attention.

the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

Fix APFloat::getLargest so that it actually returns the correct value.  Found by accident while reviewing a patch to nearby code.

llvm-svn: 141816

Fix APInt::operator*= so that it computes the correct result for large integers where there is unsigned overflow.  Fix APFloat::toString so that it doesn't depend on the incorrect behavior in common cases (and computes the correct result in some rare cases).  Fixes PR11086.

NULL cannot be portably used as the last argument to a function with __attribute((sentinel)), even though it usually works.  Use (void*)0 instead.  PR11002.

It is an endian-aware helper that can read data from a StringRef. It will
come in handy for DWARF parsing. This class is inspired by LLDB's
DataExtractor, but is stripped down to the bare minimum needed for DWARF.

Comes with unit tests!

In the case of EDInstInfo, this would actually cause a bug when -1 became 255
and was then compared >=0 in llvm-mc/Disassembler.cpp.

The APFloat "Zero" test was actually calling the
APFloat(const fltSemantics &, integerPart) constructor, and EXPECT_EQ was
treating 0 and -0 as equal.
