There is no constant propagation for globals with weak linage, right?
Otherwise, it won't work. My concern is that there may be optimization passes
which do not respect the weak linkage and uses the incorrect default value for
OpenCL or HIP. Therefore I am not very confident to enable this for OpenCL or
HIP unless these variables have the correct value based on the compilation
options.

+ AddGlobal("__oclc_ISA_version", Minor + Major * 1000, 32);
+ AddGlobal("__oclc_ABI_version", 400, 32);
+}

should be determined by the code object version option.
================
Comment at: clang/test/CodeGen/amdgcn-occl-constants.c:8
+// CHECK: @__oclc_daz_opt = weak_odr hidden local_unnamed_addr addrspace(4)
constant i8 0, align 1
+// CHECK: @__oclc_wavefrontsize64 = weak_odr hidden local_unnamed_addr
addrspace(4) constant i8 1, align 1
+// CHECK: @__oclc_finite_only_opt = weak_odr hidden local_unnamed_addr
addrspace(4) constant i8 0, align 1
----------------
need a check for __oclc_wavefrontsize64=0 for gfx1030
