52322e7b8b MC/X86: Lower TAILCALLd[64] to JMP_1, to allow relaxation and to avoid same 
prefix byte problem as in r104062.
 - As a total hack to keep the TAILCALL markers in the output, which some tests depend on, this invents a new TAILJMP_1 instruction.

6db0363bdc make mcinstlower remove all but the first operand to CALL64pcrel32. 
The register use operands (e.g. the first argument is passed in a 
register) is currently being modeled as a normal register use,
instead of correctly being an implicit use.  This causes the operand
to get propagated onto the mcinst, which was causing the encoder to
emit a rex prefix byte, which generates an invalid call.

This fixes rdar://7998435

16d8f8bd91 I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename it 
to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is
the opposite, for future use by dragonegg.

Streamerizes PIC16 debug info, which escaped my attention.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

11d53c129f rearrange MCContext ownership. Before LLVMTargetMachine created it 
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.
