[ELF] - EhFrame.cpp: cover personality encoding handling code with the test cases. CIEs augmentation string can have 'P' character, what means the next byte is the personality encoding, a DW_EH_PE_xxx value. This is followed by a pointer to the personality function. We had the support of the different encodings earlier, but had no test cases. This change adds coverage of DW_EH_PE_absptr/DW_EH_PE_signed/DW_EH_PE_udata2/DW_EH_PE_sdata2 and DW_EH_PE_udata8/DW_EH_PE_sdata8 cases for place below: https://github.com/llvm-mirror/lld/blob/master/ELF/EhFrame.cpp#L123 llvm-svn: 335969
