Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and -mno-shared). HasAbsoluteCall is not implemented but HasABICall is the default for o32 ABI. Now, both should help into a more accurate relocation types implementation. Added IsLinux is needed to choose between asm directives. Instruction name strings cleanup. AsmPrinter improved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53551 91177308-0d34-0410-b5e6-96231b3b80d8
