ARM IAS: (partially) support .arch_extension directive This adds a partial implementation of the .arch_extension directive to the integrated ARM assembler. There are a number of limitations to this implementation arising from the target backend support rather than the implementation itself. Namely, iWMMXT (v1 and v2), Maverick, and XScale support is not present in the ARM backend. Currently, there is no check for A-class only (needed for virt), and no ARMv6k detection (needed for os and sec). The remainder of the extensions are fully supported. llvm-svn: 201471

The errors for Armv7-a and Thumbv7-a will always include "ARM" or "THUMB" respectively so they need their own CHECK prefix, making CHECK-V7 redundant. mp: Behaviour is dependent on whether the triple is v6/v7/v7M regardless of being Arm or Thumb.

[ARM] Use new assembler diags for ARM This converts the ARM AsmParser to use the new assembly matcher error reporting mechanism, which allows errors to be reported for multiple instruction encodings when it is ambiguous which one the user intended to use. By itself this doesn't improve many error messages, because we don't have diagnostic text for most operand types, but as we add that then this will allow more of those diagnostic strings to be used when they are relevant.

@ CHECK-THUMBv6: error: instruction requires: divide in THUMB armv8m.base
ARM: correct handling of features in arch_extension The subtarget information is the ultimate source of truth for the feature set that is enabled at this point. We would previously not propagate the feature information to the subtarget. While this worked for the most part (features would be enabled/disabled as requested), if another operation that changed the feature bits was encountered (such as a mode switch via a .arm or .thumb directive), we would end up resetting the behaviour of the architectural extensions. Handling this properly requires a slightly more complicated handling. We need to check if the feature is now being toggled. If so, only then do we toggle the features. In return, we no longer have to calculate the feature bits ourselves. The test changes are mostly to the diagnosis, which is now more uniform (a nice side effect!). Add an additional test to ensure that we handle this case properly. Thanks to Nico Weber for alerting me to this issue! llvm-svn: 214057
