35934f8100 [AMDGPU] Remove hardcoded address space value from AMDGPULibFunc
AMDGPULibFunc hardcodes address space values of the old address space mapping,
which causes invalid addrspacecast instructions and undefined functions in
APPSDK sample MonteCarloAsianDP.

This patch fixes that.

9643e6bd78 [AMDGPU] Ported and adopted AMDLibCalls pass
The pass does simplifications of well known AMD library calls.
If given -amdgpu-prelink option it works in a pre-link mode which
allows to reference new library functions which will be linked in
later.

In addition it also used to process traditional AMD option
-fuse-native which allows to replace some of the functions with
their fast native implementations from the library.

The necessary glue to pass the prelink option and translate
-fuse-native is to be added to the driver.
