For the Family 6 switch in sys::getHostCPUName, an unrecognized model was
reported as "i686". That's a really bad default since it means that new
CPUs will be treated as if they can only use 32-bit code. This just looks
at the cpuid extended feature flag for 64 bit support, and if that is set,
it uses a default x86-64 cpu. Similar logic is already used for the Family
15 code. <rdar://problem/11314502>

This lets you save the textual representation of the LLVM IR to a file.
Before this patch it could only be printed to STDERR from llvm-c.

The getPointerRegClass() hook will return GR32_TC, or whatever is
appropriate for the current function.

My previous change to install llvm-config-host for cross-builds resulted
in that file being installed even when the normal llvm-config was not
installed, e.g., when building the install-clang target. Daniel suggested
this alternative, which solves the immediate problem and also avoids the gunk
in the top-level makefile.

When a combine twiddles an extract_vector, care should be take to preserve
the type of the index operand. No luck extracting a reasonable testcase,
unfortunately.

Revert this for now since I don't know enough cmake to fix it properly.

- Currently this leaves us with less build system support (e.g., installing man pages) for the docs than is desired. I'm working on fixing this, but it may take a while. If someone finds this particularly egregious let me know and I will prioritize it.

I still left another fixme regarding alignment, because I'm unsure how to remove that code without breaking things

replace the operands of expressions with only one use with undef and generate
a new expression for the original without using RAUW to update the original.
Thus any copies of the original expression held in a vector may end up
referring to some bogus value - and using a ValueHandle won't help since there
is no RAUW. There is already a mechanism for getting the effect of recursion
non-recursively: adding the value to be recursed on to RedoInsts. But it wasn't
being used systematically. Have various places where recursion had snuck in at
some point use the RedoInsts mechanism instead. Fixes PR12169.

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.
