This method is very hot, it is called when emitting diagnostics, in -E mode
and for many #pragma handlers. It scans through the whole source file to
count newlines, records and caches them in a vector.

The speedup from vectorization isn't very large, as we fall back to bytewise
scanning when we hit a newline. There might be a way to avoid leaving the sse
loop but everything I tried didn't work out because a call to push_back
clobbers xmm registers.

About 2% speedup on average on "clang -E > /dev/null" of all .cpp files in
clang's lib/Sema.

disassembler requires a MCSubtargetInfo and a
MCInstrInfo to exist in order to initialize the
instruction printer and disassembler; however,
although the printer and disassembler keep
references to these objects they do not own them.
Previously, the MCSubtargetInfo and MCInstrInfo
objects were just leaked.

I have extended LLVMDisasmContext to own these
objects and delete them when it is destroyed.

Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Fixed ModuleList::FindTypes() so that when a symbol context is supplied that contains a valid module, it will search that module first, then if we are still looking for matches (we have found less that "max_matches"), search in all of the other modules as well.

In a prior commit, I changed the parameters around on a ModuleList::FindTypes where the old parameters that existing clients were using would have been compatible, so I renamed ModuleList::FindTypes to ModuleList::FindTypes2. Then I made fixes and verified I updated and fixed all client code, but I forgot to rename the function back to ModuleList::FindTypes(). I am doing that now and also cleaning up the C++ dynamic type code a bit.

simplification has been performed. This is a bit less efficient
(requires another ilist walk of the basic blocks) but shouldn't matter
in practice. More importantly, it's just too much work to keep track of
all the various ways the return instructions can be mutated while
simplifying them. This fixes yet another crasher, reported by Daniel
Dunbar.

inside of a sysroot targeting a system+sysroot which is "similar" or
"compatible" with the host system. This shows up when trying to build
system images on largely compatible hardware as-if fully cross compiled.

The problem is that previously we *perfectly* mimiced GCC here, and it
turns out GCC has a bug that no one has really stumbled across. GCC will
try to look in thy system prefix ('/usr/local' f.ex.) into which it is
instaled to find libraries installed along side GCC that should be
preferred to the base system libraries ('/usr' f.ex.). This seems not
unreasonable, but it has a very unfortunate consequence when combined
with a '--sysroot' which does *not* contain the GCC installation we're
using to complete the toolchain. That results in some of the host
system's library directories being searched during the link.

Now, it so happens that most folks doing stuff like this use
'--with-sysroot' and '--disable-multilib' when configuring GCC. Even
better, they're usually not cross-compiling to a target that is similar
to the host. As a result, searching the host for libraries doesn't
really matter -- most of the time weird directories get appended that
don't exist (no arm triple lib directory, etc). Even if you're
cross-compiling from 32-bit to 64-bit x86 or vice-versa, disabling
multilib makes it less likely that you'll actually find viable libraries
on the host. But that's just luck. We shouldn't rely on this, and this
patch disables looking in the system prefix containing the GCC
installation if that system prefix is *outside* of the sysroot. For
empty sysroots, this has no effect. Similarly, when using the GCC
*inside* of the sysroot, we still track wherever it is installed within
the sysroot and look there for libraries. But now we can use a cross
compiler GCC installation outside the system root, and only look for the
crtbegin.o in the GCC installation, and look for all the other libraries
inside the system root.

This should fix PR12478, allowing Clang to be used when building
a ChromiumOS image without polluting the image with libraries from the
host system.
