  [Sparc] Move fixELFSymbolsInTLSFixups to getRelocType

fixELFSymbolsInTLSFixups walks the expression tree, which is complex and
unnecessary. As the expression must be relocatable, we can move the code
to getRelocType and just set SymA. The behavior is similar to GNU
assembler.

__tls_get_addr registery (https://reviews.llvm.org/D43271) is unnecessary
now.  SparcMCExpr::visitUsedExpr registers the symbol.
