Code object V2 had the ability to support the following queries:
- HSA_CODE_SYMBOL_INFO_KERNEL_KERNARG_SEGMENT_SIZE
- HSA_EXECUTABLE_SYMBOL_INFO_KERNEL_KERNARG_SEGMENT_SIZE
- HSA_CODE_SYMBOL_INFO_KERNEL_KERNARG_SEGMENT_ALIGNMENT
- HSA_EXECUTABLE_SYMBOL_INFO_KERNEL_KERNARG_SEGMENT_ALIGNMENT
However code object V3 onwards cannot support these as the kernel
descriptor changed. These queries need to be deprecated.
Until then return more reasonable values:
- For kernarg alignment return 16 which is the minimum alignment
required by the HSA standard.
- For kernarg size return the field from the kernel descriptor which
is a hint. If it is 0 then the compiler is not specifying the kernarg
size, or the kernel has no kernarg.
