596e61c332 [AMDGPU] Ignore call graph node which does not have function info.
While collecting reachable callees (from kernels), ignore call graph node which
does not have associated function or associated function is not a definition.

c65f3f562b [AMDGPU] Simplify collectReachableCallees. NFCI.
Don't use SCC iterators when we're only interested in reachability.
Use df_begin/df_end inline to find reachable nodes.

80fd5fa526 [AMDGPU] Replace non-kernel function uses of LDS globals by pointers.
The main motivation behind pointer replacement of LDS use within non-kernel
functions is - to *avoid* subsequent LDS lowering pass from directly packing
LDS (assume large LDS) into a struct type which would otherwise cause allocating
huge memory for struct instance within every kernel.

05289dfb62 [AMDGPU] Handle constant LDS uses from different kernels
This allows to lower an LDS variable into a kernel structure
even if there is a constant expression used from different
kernels.

5e2facb922 [AMDGPU] Fix kernel LDS lowering for constants
There is a trivial but severe bug in the recent code collecting
LDS globals used by kernel. It aborts scan on the first constant
without scanning further uses. That leads to LDS overallocation
with multiple kernels in certain cases.

82787eb228 [AMDGPU] Move LDS lowering related utility functions to a separate utils file.
Move some utility functions which are used within LDS lowering pass to a separate utils
file so that other LDS related passes can make use of them when required.
