Implement call lowering without parameters on AIX Summary:dd This patch implements call lowering for calls without parameters on AIX as initial support. Reviewers: sfertile, hubert.reinterpretcast, aheejin, efriedma Differential Revision: https://reviews.llvm.org/D61948 llvm-svn: 361669

[PowerPC][AIX]Add lowering of MCSymbol MachineOperand. Adds machine operand lowering for MCSymbolSDNodes to the PowerPC backend. This is needed to produce call instructions in assembly for AIX because the callee operand is a MCSymbolSDNode. The test is XFAIL'ed for asserts due to a (valid) assertion in PEI that the AIX ABI isn't supported yet. Differential Revision: https://reviews.llvm.org/D63738 llvm-svn: 367133

[AIX] Implement function descriptor on SDAG Summary: (1) Function descriptor on AIX On AIX, a called routine may have 2 distinct symbols associated with it: * A function descriptor (Name) * A function entry point (.Name) The descriptor structure on AIX is the same as those in the ELF V1 ABI: * The address of the entry point of the function. * The TOC base address for the function. * The environment pointer. The descriptor symbol uses the same name as the source level function in C. The function entry point is analogous to the symbol we would generate for a function in a non-descriptor-based ABI, except that it is renamed by prepending a ".". Which symbol gets referenced depends on the context: * Taking the address of the function references the descriptor symbol. * Calling the function references the entry point symbol. (2) Speaking of implementation on AIX, for direct function call target, we create proper MCSymbol SDNode(e.g . ".foo") while constructing SDAG to replace original TargetGlobalAddress SDNode. Then down the path, we can take advantage of this MCSymbol.
