OvmfPkg: Use Xcode5 version of CpuExceptionHandlerLib for CLANGDWARF
The CLANGDWARF toolchain has the same problem as XCODE5 linking
CpuExceptionHandlerLib. So, use the
Xcode5SecPeiCpuExceptionHandlerLib.inf when building with the CLANGDWARF
toolchain.
Since the difference is that the non-Xcode5 version uses `mov` while the
Xcode5 version uses `lea`, they can be merged in future with the single
version using `lea`.
[ardb: the main difference is that the 'mov' instructions result in
absolute symbol references, which are necessary because the code
in question is copied in memory independently from the code that
carries the symbols it refers to. The Xcode5 version has
additional runtime handling to fix up the copied code with the
correct absolute references.]
