target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.

First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

It has only one user. This eliminates the last include of
config.h from the public headers -- ideally, config.h
shouldn't even be installed by `make install` anymore.

llvm-svn: 133713

Replace it with llvm-config.h, which defines a subset of
config.h's macros "so that they can be in exported headers 
and won't override package specific directives", e.g.,
PACKAGE_NAME.

Endian.h wasn't using any macros at all though, so just delete
the include there instead.

llvm-svn: 133712

It's now replaced with a simple ifdef _MSC_VER in the one
place it's needed (clang's FileManager.h header).

Take #2. Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.
