Evan Cheng 8c886a40d2 Combine all MC initialization routines into one. e.g. InitializeX86MCAsmInfo, 
InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

Evan Cheng 2129f59637 Introduce MCCodeGenInfo, which keeps information that can affect codegen 
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

Dylan Noblesmith 5688b2b25b remove CMake mode_t define 
It's now replaced with a simple ifdef _MSC_VER in the one
place it's needed (clang's FileManager.h header).

NAKAMURA Takumi 4471f82e91 Windows/DynamicLibrary.inc: Clean up ELM_Callback. We may check the decl instead of the versions of individual libraries. 
autoconf: Add checking ELM_Callback decl for mingw32 and mingw-w64.
cmake/config-ix.cmake: Add checking ELM_Callback decl for win32.

Oscar Fuentes f2ab92833a Handle changing of LLVM_ENABLE_FFI. 
If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it
off, the build will fail in lib/ExecutionEngine/Interpreter because
Interpreter will try still to #include <ffi/ffi.h>, but there are no
include_directories(${FFI_INCLUDE_DIR}) now.

This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if
LLVM_ENABLE_FFI=0. This forces CMake to update config.h.

NAKAMURA Takumi 189111808e lib/Support/Errno.cpp: Check strerror_s() with HAVE_DECL_STRERROR_S in config.h.*. 
AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h.

FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()).
FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future.

NAKAMURA Takumi 03a541f5c4 Windows/DynamicLibrary.inc: Split explicit symbols into explicit_symbols.inc. 
config.h.* have conditions whether each symbol is defined or not.
Autoconf and CMake may check symbols in libgcc.a for JIT on Mingw.

Oscar Fuentes f4202ba475 Changes for building Clang and others using LLVM as an external 
library.

Installs tblgen (required by Clang).

Translates handling of user settings and platform-dependant options to
its own file, where it can included by another project.

Installs the .cmake files required by projects like Clang.

config.h was generated, so it had no effect on it.

Chris Lattner 1ef5e84c31 Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Oscar Fuentes e16dc06159 Fix cmake build without native target selected. 
The cmake (+ MSVC) build is broken if you don't select your native
target.

e.g. 'cmake -D LLVM_TARGETS_TO_BUILD="MyNonNativeTarget" .'

This is because cmake currently sets the LLVM_NATIVE_* definitions
regardless of whether the native target is selected (causing build
errors).

that like to randomly define things like "X86", regenerate autoconf bits
and update cmake.
