[SystemZ] Fix FPR dwarf numbering The dwarf FPR numbers are supposed to have the order F0, F2, F4, F6, F1, F3, F5, F7, F8, etc., which matches the pairing of registers for long doubles. E.g. a long double stored in F0 is paired with F2. llvm-svn: 212701

# 00000000 0000000000000014 00000000 CIE
Emit DWARF3 call frame information when DWARF3+ debug info is requested Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the newer CIE version when we are emitting DWARF 3 or 4. This will not reduce compatibility, as we already emit other DWARF3/4 features, and is worth doing as the DWARF3 spec removed some ambiguities in the interpretation of call frame information. It also fixes a minor bug where the "return address" field of the CIE was encoded as a ULEB128, which is only valid when the CIE version is 3. There are no test changes for this, because (as far as I can tell) none of the platforms that we test have a return address register with a DWARF register number >127. llvm-svn: 211272
