We should be able to run the pass multiple times without breaking
anything. If we still need to track these for some reason, we could
replace with new entries for the kernels.
HSA runtime fails to find the symbols for Init and Fini kernels as
they mark with internal linkage, changing the linkage to external
to fix those errors.

This patch introduces a new code object metadata field, ".kind"
which is used to add support for init and fini kernels.
HSAStreamer will use function attributes, "device-init" and
"device-fini" to distinguish between init and fini kernels from
the regular kernels and will emit metadata with ".kind" set to
"init" and "fini" respectively.
To reduce the number of init and fini kernels, the ctors and
dtors present in the llvm's global.ctors and global.dtors lists
are called from a single init and fini kernel respectively.
