This patch allows us to use cmake to specify a cross compiler for Hexagon.

In particular, the patch adds a missing case for the target Hexagon in
cmake/config-ix.cmake, and it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE
variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them
available at configure time. Here is the command line that I have used to test
my patches:

$ cmake -G Ninja -D BUILD_SHARED_LIBS:BOOL=ON -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu -D LLVM_ENABLE_PIC:BOOL=OFF ..
$ ninja check

cmake: Add LLVM_HOSTTRIPLE. For now, it is same as TARGET_TRIPLE.

dealing in the host triple, be honest about it and document the decision
to default the target triple to the host triple unless overridden.

Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

Use 'check_symbol_exists' instead of 'check_function_exists' for finding isatty.  This change allows Xcode generated projects to have HAVE_ISATTY to be properly defined.

Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

Rename createAsmInfo to createMCAsmInfo and move registration code to MCTargetDesc to prepare for next round of changes.

It's now replaced with a simple ifdef _MSC_VER in the one

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.

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.

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.

config.h.* have conditions whether each symbol is defined or not.
Autoconf and CMake may check symbols in libgcc.a for JIT on Mingw.
