Ordinary patch for PR1255.
Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object.
Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported.

Note that support for rvalue references does not imply support
for the full set of move-related STL operations.
I've preserved support for an odd little thing in insert() where
we're trying to support inserting a new element from an existing
one. If we actually want to support that, there's a lot more we
need to do: insert can call either grow or push_back, neither of
which is safe against this particular use pattern.

This way we can enable the POD-like class optimization for a lot more classes,
saving ~120k of code in clang/i386/Release+Asserts when selfhosting.

The problem is that the struct file_status on UNIX systems has two
members called st_dev and st_ino; those are also members of the
struct stat, and they are reserved identifiers which can also be
provided as #define (and this is the case for st_dev on Hurd).
The solution (attached) is to rename them, for example adding a
"fs_" prefix (= file status) to them.

through the use of 'fpmath' metadata. Currently this only provides a 'fpaccuracy'
value, which may be a number in ULPs or the keyword 'fast', however the intent is
that this will be extended with additional information about NaN's, infinities
etc later. No optimizations have been hooked up to this so far.

and retrieving it from instructions. I don't have a use for this but is seems
logical for it to exist. While there, remove some 'const' markings from methods
which are in fact 'const' in practice, but aren't logically 'const'.

in TargetLowering. There was already a FIXME about this location being
odd. The interface is simplified as a consequence. This will also make
it easier to change TLS models when compiling with PIE.

The empty 1-argument operator delete is for the benefit of the
destructor. A couple of spot checks of running yaml-bench under
valgrind against a few of the files under test/YAMLParser did
not reveal any leaks introduced by this change.

This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.
The test case checks for both big and little endian flavors.

visitor will now visit a CallInst and an InvokeInst with
instruction-specific visitors, then visit a generic CallSite visitor,
then delegate back to the Instruction visitor and the TerminatorInst
visitors depending on whether a call or an invoke originally. This will
be used in the soon-to-land inline cost rewrite.

a more consistent ordering.
Suggestions on still better / more consistent formatting would be
welcome. I'm actually tempted to use a macro to define all of the
delegate methods...

* Add enums and structures for GNU version information.
* Implement extraction of that information on a per-symbol basis (ELFObjectFile::getSymbolVersion).
* Implement a generic interface, GetELFSymbolVersion(), for getting the symbol version from the ObjectFile (hides the templating).
* Have llvm-readobj print out the version, when available.
* Add a test for the new feature: readobj-elf-versioning.test

compilers. It seems that GCC 4.3 (and likely older) simply aren't going
to do SFINAE on non-type template parameters the way Clang and modern
GCCs do...
Now we detect the implicit conversion to an integer type, and then
blacklist classes, pointers, and floating point types. This seems to
work well enough, and I'm hopeful will return the bots to life.

With this change, the pattern used here is *extremely* close to the
pattern used elsewhere in the file, so I'm hoping it survives the
build-bots.

template argument and an *implicit* conversion from '0' to a null
pointer. For some bizarre reason, GCC 4.3.2 thinks that the cast to
'(T*)' is invalid inside of an enumerator's value... which it isn't but
whatever. ;] This pattern is used elsewhere in the type_traits header
and so hopefully will survive the wrath of the build bots.
