[SystemZ] Fix trap issue and enable expensive checks. The isBarrier/isTerminator flags have been removed from the SystemZ trap instructions, so that tests do not fail with EXPENSIVE_CHECKS. This was just an issue at -O0 and did not affect code output on benchmarks. (Like Eli pointed out: "targets are split over whether they consider their "trap" a terminator; x86, AArch64, and NVPTX don't, but ARM, MIPS, PPC, and SystemZ do. We should probably try to be consistent here.". This is still the case, although SystemZ has switched sides). SystemZ now returns true in isMachineVerifierClean() :-) These Generic tests have been modified so that they can be run with or without EXPENSIVE_CHECKS: CodeGen/Generic/llc-start-stop.ll and CodeGen/Generic/print-machineinstrs.ll Review: Ulrich Weigand, Simon Pilgrim, Eli Friedman https://bugs.llvm.org/show_bug.cgi?id=33047 https://reviews.llvm.org/D34143 llvm-svn: 306106

CodeGen/LLVMTargetMachine: Refactor ISel pass construction; NFCI - Move ISel (and pre-isel) pass construction into TargetPassConfig - Extract AsmPrinter construction into a helper function Putting the ISel code into TargetPassConfig seems a lot more natural and both changes together make make it easier to build custom pipelines involving .mir in an upcoming commit. This moves MachineModuleInfo to an earlier place in the pass pipeline which shouldn't have any effect. llvm-svn: 304754

[TargetPassConfig] Feature generic options to setup start/stop-after/before This patch refactors the code used in llc such that all the users of the addPassesToEmitFile API have access to a homogeneous way of handling start/stop-after/before options right out of the box. In particular, just invoking addPassesToEmitFile will set the proper pipeline without additional effort (modulo parsing a .mir file if the start-before/after options are used. NFC.
