[ARM] Avoid switching ARM/Thumb mode on .arch/.cpu directive
When we see a .arch or .cpu directive, we should try to avoid switching
ARM/Thumb mode if possible.
If we do have to switch modes, we also need to emit the correct mapping
symbol for the new ISA. We did not do this previously, so could emit
ARM code with Thumb mapping symbols (or vice-versa).
The GAS behaviour is to always stay in the same mode, and to emit an
error on any instructions seen when the current mode is not available on
the current target. We can't represent that situation easily (we assume
that Thumb mode is available if ModeThumb is set), so we differ from the
GAS behaviour when switching to a target that can't support the old
mode. I've added a warning for when this implicit mode-switch occurs.

is_integral_or_enum ❥ enum class ⇒ hashable enum class
Summary:
As discussed in D18775 making AtomicOrdering an enum class makes it non-hashable, which shouldn't be the case. Hashing.h defines hash_value for all is_integral_or_enum, but type_traits.h's definition of is_integral_or_enum only checks for *inplicit* conversion to integral types which leaves enum classes out and is very confusing because is_enum is true for enum classes.
This patch:
- Adds a check for is_enum when determining is_integral_or_enum.
- Explicitly converts the value parameter in hash_value to handle enum class hashing.
Note that the warning at the top of Hashing.h still applies: each execution of the program has a high probability of producing a different hash_code for a given input. Thus their values are not stable to save or persist, and should only be used during the execution for the construction of hashing datastructures.

[Perf-Training] Reworked workflow improvements for order-file generation
This is re-landing r260742. I've reworked the conditionals so that it only hits when targeting Apple platforms with ld64.
Original Summary:
With this change generating clang order files using dtrace uses the following workflow:
cmake <whatever options you want>
ninja generate-order-file
ninja clang
This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.
CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.

[CMake] Make llvm_ExternalProject always call the build action
This makes it so that when running 'ninja test-suite' from the top-level LLVM ninja build it *always* re-runs the ninja command in the test-suite directory.
This mechanism is required because the top-level ninja file doesn't have a view into the subdirectory dependency tree, so it can't know what, if anything, needs to be rebuilt.

Support the Nodebug emission kind for DICompileUnits.
Sample-based profiling and optimization remarks currently remove
DICompileUnits from llvm.dbg.cu to suppress the emission of debug info
from them. This is somewhat of a hack and only borderline legal IR.
This patch uses the recently introduced NoDebug emission kind in
DICompileUnit to achieve the same result without breaking the Verifier.
A nice side-effect of this change is that it is now possible to combine
NoDebug and regular compile units under LTO.

This is in preparation for tail duplication during block placement. See D18226.
This needs to be a utility class for 2 reasons. No passes may run after block

it must be interleaved with placement, and can't be separated out into its own
pass. The original pass is still useful, and now runs by delegating to the
