Most files remain in a common amdgpu directory.
Also switches barriers to to use convergent,
and use llvm.amdgcn.s.barrier.
This now requires 3.9/trunk to build amdgcn.

This makes it possible for runtime implementations to disable
subnormal handling at runtime.
When this flag is enabled, decisions about how to handle subnormals
in the library will be controlled by an external variable called
__CLC_SUBNORMAL_DISABLE.
Function implementations should use these new helpers for querying subnormal
support:
__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();
In order for the library to link correctly with this feature,
users will be required to either:
1. Insert this variable into the module (if using the LLVM/Clang C++/C APIs).
2. Pass either subnormal_disable.bc or subnormal_use_default.bc to the
linker. These files are distributed with liblclc and installed to
$(installdir). e.g.:
llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_disable.bc
or
llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_use_default.bc
If you do not supply the --enable-runtime-subnormal then the library
behaves the same as it did before this commit.
In addition to these changes, the patch adds helper functions that
should be used when implementing library functions that need
special handling for denormals:
__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

Some functions are implemented using hand-written LLVM IR, and
LLVM assembly format is allowed to change between versions, so we
should require a specific version of LLVM.

We use ${DESTDIR} syntax now instead of $(DESTDIR) because that syntax
works both is the shell (at least it does for bash) and for make (at
least it does for GNU Make)

The C++ compiler used to build prepare-builtins
may differ from the llvm/clang for which we are
building libclc.
Use 'clang++' as the default compiler.

There are two implementations of nextafter():
1. Using clang's __builtin_nextafter. Clang replaces this builtin with
a call to nextafter which is part of libm. Therefore, this
implementation will only work for targets with an implementation of
libm (e.g. most CPU targets).
2. The other implementation is written in OpenCL C. This function is
known internally as __clc_nextafter and can be used by targets that
don't have access to libm.

libclc is ABI-agnostic, and $prefix/lib/pkgconfig causes issues
on multilib setups. Using $prefix/share/pkgconfig allows us to reuse
a single libclc build across all system ABIs.

Targets can override generic implementations by adding a file called
OVERRIDES in $(TARGET_DIR)/lib and listing the generic implementations
that it wants to override. For example, to override get_group_id() and
get_global_size() you would add these lines to the OVERRIDES file:
workitem/get_group_id.cl
workitem/get_global_size.cl

- First introducing a versioning scheme
- Add --libexecdir, --includedir and --pkgconfigdir and prefill them as well as --prefix
- Build all targets by default
- Create clc.pc and install it in $pkgconfigdir
- Use clang++ instead of c++
- Rename builtins.bc to built_libs/$triple.bc and install them in $libexecdir
- Includes are installed recursively to $includedir
- Finally add $(DESTDIR) for 'make install'
