[mips] Use llvm-mc -triple option instead of combination of arch,target-abi,mcpu. NFC llvm-svn: 348914

[mips][ias] Fix N32 and N64 .cprestore directive when inside .set noat region. Summary: r268058 unintentionally made the retrieval of the current assembler temporary unconditional. This was fine for the existing tests but it broke the cases where the assembler temporary is not needed (N32/N64 or not PIC) and is unavailable due to a '.set noat' directive. This fixes FreeBSD's libc. Reviewers: emaste, sdardis, seanbruno Subscribers: dsanders, emaste, sdardis, llvm-commits Differential Revision: http://reviews.llvm.org/D20093 llvm-svn: 269179

[test] llvm/test/: change llvm-objdump single-dash long options to double-dash options As announced here: http://lists.llvm.org/pipermail/llvm-dev/2019-April/131786.html Grouped option syntax (POSIX Utility Conventions) does not play well with -long-option A subsequent change will reject -long-option.

[mips][ias] Fix O32 .cprestore directive when inside .set noat region and offset is in range. Summary: This expands on r269179 to fix an additional case that was not covered by our tests. The assembler temporary is not needed when the .cprestore offset fits inside a simm16 and it is not an error to use it inside a '.set noat' in this case.
