[mips] Notify user that `-mabicalls` is ignored on non-PIC N64 ABI The -mabicalls option does not make sense in the case of non position independent code for the N64 ABI. After this change the driver shows a warning that -mabicalls is ignored in that case. Differential revision: https://reviews.llvm.org/D36550 llvm-svn: 310613

// REQUIRES: mips-registered-target
[mips] Improve handling of -fno-[pic/PIC] option In order to disable PIC and to match GCC behaviour, -mno-abicalls option is neccessary. When -fno-[pic/PIC] is used witout -mno-abicalls, warning is reported. An error is reported when -fno-pic or -fno-PIC is used in combination with -mabicalls. In this commit, test case is added. Depends on D44381. Differential Revision: https://reviews.llvm.org/D44684 llvm-svn: 331640
