[clang][Sparc] Fix __builtin_extract_return_addr etc.
While investigating the failures of `symbolize_pc.cpp` and
`symbolize_pc_inline.cpp` on SPARC (both Solaris and Linux), I noticed that
`__builtin_extract_return_addr` is a no-op in `clang` on all targets, while
`gcc` has non-default implementations for arm, mips, s390, and sparc.
This patch provides the SPARC implementation. For background see
`SparcISelLowering.cpp` (`SparcTargetLowering::LowerReturn_32`), the SPARC
psABI p.3-12, `%i7` and p.3-16/17, and SCD 2.4.1, p.3P-10, `%i7` and
p.3P-15.
Tested (after enabling the `sanitizer_common` tests on SPARC) on
`sparcv9-sun-solaris2.11`.
