TableGen: fix operand counting for aliases TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars.

[Sparc] Flush register windows for @llvm.returnaddress(1) Summary: When @llvm.returnaddress is called with a value higher than 0 it needs to read from the call stack to get the return address. This means that the register windows needs to be flushed to the stack to guarantee that the data read is valid. For values higher than 1 this is done indirectly by the call to getFRAMEADDR(), but not for the value 1.
