Previously, we used the following approach and Comgr actions
for device lib linking:
AMD_COMGR_COMPILE_SOURCE_TO_BC (compile with clang driver)
AMD_COMGR_ADD_DEVICE_LIBRARIES (link in device libs with
llvm-link API)
However, the clang driver can link in device libraries as part
of compilation, assuming a --rocm-path is set. In this context,
this is accomplished by using the following Comgr action instead:
AMD_COMGR_COMPILE_SOURCE_WITH_DEVICE_LIBS_TO_BC (compile and
link in device libs with clang driver)

Add trap handler code into runtime and compile/load during
device initialization. The current interface for trap handler in
PAL is obsolete and the new interface will be provided later.

This reverts commit f3dc04a50d.
Reason for revert: There are currently some outstanding issues with the COMPILE_SOURCE_WITH_DEVICE_LIBS Comgr action (https://ontrack-internal.amd.com/browse/SWDEV-386072). Once these LLVM issues have been resovled, we can safely re-apply this patch

This is related to SWDEV-410182, but it's not enough to fix it.
Functions from device-libs are precompiled into llvm-ir in a "target agnostic" way
(in reality, it's not 100% target agnostic, which brings us many headaches).
When linking builtins (like device-libs) from the command line, we use the flag
-mlink-builtin-bitcode. The difference between regular linking of bitcode and
this flag is that the later propagates target-specific attributes. If this
attributes are not propagated, we can end up with incosistent target attributes.
Comgr provides the action AMD_COMGR_ACTION_COMPILE_SOURCE_WITH_DEVICE_LIBS_TO_BC
for this exact reason. The old action is currently deprecated and this one should
be used.

This reverts commit a4c5c44008.
Reason for revert: Performance regressions and failures observed. Need to investigate those and before re-applying patch

This reverts commit 0969056f66.
Reason for revert: Test failures with Luxmark, blender, and Indigobench. Need to investigate before re-applying

The Comgr ADD_DEVICE_LIBRARIES action has been deprecated. In place
of the previous two-action approach:
AMD_COMGR_COMPILE_SOURCE_TO_BC
AMD_COMGR_ADD_DEVICE_LIBRARIES
We can now use a single combined action:
AMD_COMGR_COMPILE_SOURCE_WITH_DEVICE_LIBS_TO_BC
This new action more closely alings with how device library
management is done by the clang driver.

Weirdly, the `requiredDump` argument to linkLLVMBitcode was used to enable/disable
the keeping temporary bytecode files (those generated by -save-temps=all) after linking.
This patch removes this argument as there is no obvious benefit from keepeing it
(the user would only rely on -save-temps=all to control this).

Disable devlib linking when runtime links multiple objects from
the app. Otherwise devlibs will be linked twice and may cause
undefined behavior with COv5.

This patch allows to substitute binary for the opencl program. It supposed to be used as:
1. Run the opencl program with -save-temps.
2. Open the cl temp and find the following text in the program header:
Hash to override:
Source: 0xd66bcfa20e69e605
Source + clang options: 0x656a9dd8aedcbfb6
3. Create config file (ascii text) with a pair(s):
<hash> <path_to_binary_to_substitute>
where hash is the hex value from step 2 (without leading 0x), you can use either hash
depending on what you're going to match:
only the source text of the program or along with it's clang options.
4. Set the env variable AMD_OCL_SUBST_OBJFILE to the path of your config file.
5. Rerun the opencl program.

In adition to removing the HSAIL logic from the ROCm backend, guard all
of the HSAIL includes in the common layer behind the WITH_COMPILER_LIB
define. This is to avoid including HSAIL headers when building with
no support for it.
In common logic replace the use of the aclType enum with the new
Program::file_type_t enum. This is essentially a local copy of the HSAIL
enum to avoid including any HSAIL headers.

- Correct GSL path to report targets using the TargetID syntax.
- Correct GSL path to check compatibility of code objects when
loading.
- Add concept of an device isa and create a registery used by ROCm,
PAL and GSL.
- Support XNACK and SRAMECC target features consistently for PAL and ROCm.
- Correct logic for NullDevices and asserts to avoid memory coruption.
- Allow all NullDevices to be created for HIP.
- Numerous other code improvements.
