[ARM] Define subtarget feature strict-align. This commit defines subtarget feature strict-align and uses it instead of cl::opt -arm-strict-align to decide whether strict alignment should be forced. Also, remove the logic that was checking the OS and architecture as clang is now responsible for setting strict-align based on the command line options specified and the target architecute and OS. rdar://problem/21529937 http://reviews.llvm.org/D11470 llvm-svn: 243493

ARM: fixup more tests to specify the target more explicitly This changes the tests that were targeting ARM EABI to explicitly specify the environment rather than relying on the default. This breaks with the new Windows on ARM support when running the tests on Windows where the default environment is no longer EABI. Take the opportunity to avoid a pointless redirect (helps when trying to debug with providing a command line invocation which can be copy and pasted) and removing a few greps in favour of FileCheck. llvm-svn: 205541

[DAGCombiner] If a TokenFactor would be merged into its user, consider the user later. Summary: A number of optimizations are inhibited by single-use TokenFactors not being merged into the TokenFactor using it. This makes we consider if we can do the merge immediately. Most tests changes here are due to the change in visitation causing minor reorderings and associated reassociation of paired memory operations. CodeGen tests with non-reordering changes: X86/aligned-variadic.ll -- memory-based add folded into stored leaq value. X86/constant-combiners.ll -- Optimizes out overlap between stores. X86/pr40631_deadstore_elision -- folds constant byte store into preceding quad word constant store.
