Currently HIP still uses offload bundler for non-rdc mode for the new offload
driver.
This patch switches to use offload wrapper for non-device-only non-rdc mode
when new offload driver is enabled.
This makes the rdc and non-rdc compilation more consistent and speeds up
compilation since the offload wrapper supports parallel compilation for
different GPU arch's.
It is implemented by adding a linker wrapper action for each assemble action of
input file. Linker wrapper action differentiates this special type of work vs
normal linker wrapper work by the fle type. This type of work results in object
instead of image. The linker wrapper adds "-r" for it and only includes the
object file as input, not the host libraries.
For device-only non-RDC mode, the new driver keeps the original behavior.

Subject: [PATCH] [HIP] use offload wrapper for non-device-only non-rdc
Currently HIP still uses offload bundler for non-rdc mode for
the new offload driver.
This patch switches to use offload wrapper for non-device-only
non-rdc mode when new offload driver is enabled.
This makes the rdc and non-rdc compilation more consistent
and speeds up compilation since the offload wrapper supports
parallel compilation for different GPU arch's.
It is implemented by adding a linker wrapper action for
each assemble action of input file. Linker wrapper action
differentiates this special type of work vs normal
linker wrapper work by the fle type. This type of work
results in object instead of image. The linker wrapper
adds "-r" for it and only includes the object file
as input, not the host libraries.
For device-only non-RDC mode, the new driver keeps the
original behavior.
