For some reason GCC decided to call the feature rdrnd instead of rdrand,
which requires translating it for LLVM.

use template type diffing.

Also updated the internal manual and test cases for correctly keeping the bold

add interface for removing a FileEntry from the cache.
Forces a re-read the contents from disk, e.g. because a tool (like cling) wants to pick up a modified file.

comparison between two templated types when they both appear in a diagnostic.
Type elision will remove indentical template arguments, which can be disabled
with -fno-elide-type.  Cyan highlighting is applied to the differing types.

For more formatting, -fdiagnostic-show-template-tree will output the template
type as an indented text tree, with differences appearing inline. Template
tree works with or without type elision.

express library-level dependencies within Clang.

This is no more verbose really, and plays nicer with the rest of the
CMake facilities. It should also have no change in functionality.

they support weak class import, but it's easy enough for them to opt in.

target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

r158085 added some logic to track predefined declarations.  The main reason we
had predefined declarations in the input was because the __builtin_va_list
declarations were injected into the preprocessor input.  As of r158592 we 
explicitly build the __builtin_va_list declarations.  Therefore the predefined
decl tracking is no longer needed.

The target specific __builtin_va_list types are now explicitly built instead
of injecting strings into the preprocessor input.

This functionality is based on what is done on ARM, and enables selecting PPC CPUs
in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86),
-mcpu=native support was added. This uses the host cpu detection from LLVM
(which will also soon be updated by refactoring code currently in backend).

In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM.
A few preprocessor defines for common CPU types have been added.

from Tom Honermann!

llvm-svn: 158211

In standard C since C89, a 'translation-unit' is syntactically defined to have
at least one "external-declaration", which is either a decl or a function
definition. In Clang the latter gives us a declaration as well.

The tricky bit about this warning is that our predefines can contain external
declarations (__builtin_va_list and the 128-bit integer types). Therefore our
AST parser now makes sure we have at least one declaration that doesn't come
from the predefines buffer.

Also, remove bogus warning about empty source files. This doesn't catch source
files that only contain comments, and never fired anyway because of our
predefines.
