64-bit sparc codegen.  Patch by Nathan Keynes!

llvm-svn: 95293

Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
This fixes 483.xalancbmk (with tail call opt).

Restore \n removed in latest MC frenzy.

Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.

even, say, emit them.

Allow all types of callee's to be tail called. But avoid automatic tailcall if the callee is a result of bitcast to avoid losing necessary zext / sext etc.

ByVal frame object size should be that of the byval argument, not the size of the type which is just a pointer. This is not known to break stuff but is wrong nevertheless.
