25eba399cb Change the chain input of nodes that load the address of a function. This change 
enables SelectionDAG::getLoad at MipsISelLowering.cpp:1914 to return a
pre-existing node instead of redundantly create a new node every time it is
called.

5c10b63969 Make the generated InitXXXMCRegisterInfo function "static inline", so it doesn't get emitted into multiple object files. 
This caused linker errors when linking both libLLVMX86Desc and libLLVMX86CodeGen
into a single binary (for example when building a monolithic libLLVM shared library).

a347f85dbe Starting to refactor Target to separate out code that's needed to fully describe 
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.

4e5885dc0f Don't include config.h in public headers 
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.

f2a58425cd lit support for REQUIRES: asserts. 
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.
