[TSan] Improve handling of stack pointer mangling in {set,long}jmp, pt.2

Description

[TSan] Improve handling of stack pointer mangling in {set,long}jmp, pt.2

Switch LongJmp over to lookup JmpBuf via plain old (unmangled) SP.
This makes the computation of mangled SPs in the TSan assembly files
unnecessary, which will be cleaned up in follow-up revisions.
