This patch fixes two issues:
(a) The target size is the pointer size and
host size is the variable size itself; thus, it fails often.
(b) Only the host variable has the link-var bit flip, hence,
we need to check this one not the target var's size.
With this patch, the test case passes on AMDGCN.
OK?

PS: Unfortunately, all those patches do not help with nvptx,
which still fails (PR 81689) at run-time startup with
ptxas /tmp/ccSRPv5o.o, line 120; error : State space mismatch between
instruction and address in instruction 'ld'
