[Sparc] Remove the support for builtin setjmp/longjmp
Summary: It is currently broken and for Sparc there is not much benefit
in using a builtin version compared to a library version. Both versions
needs to store the same four values in setjmp and flush the register
windows in longjmp. If the need for a builtin setjmp/longjmp arises there
is an improved implementation available at https://reviews.llvm.org/D50969.
