[ARM][MVE] Add invalidForTailPredication to TSFlags
Set this bit for the MVE reduction instructions to prevent a loop from
becoming tail predicated in their presence.

[RISCV] Define __riscv_cmodel_medlow and __riscv_cmodel_medany correctly
RISC-V LLVM was only implement small/medlow code model, so it defined
__riscv_cmodel_medlow directly without check.
Now, we have medium/medany code model in RISC-V back-end, it should
define according the actually code model.

[bugpoint] Add support for -Oz and properly enable -Os.
This patch adds -Oz as option and also properly enables support for -Os.
Currently, the existing check for -Os is dead, because the enclosing if
only checks of O1, O2 and O3.
There is still a difference between the -Oz pipeline compared to opt,
but I have not been able to track that down yet.

[RISCV] Add option aliases: -mcmodel=medany and -mcmodel=medlow
RISC-V GCC use -mcmodel=medany and -mcmodel=medlow, but LLVM use
-mcmodel=small and -mcmodel=medium.
Add those two option aliases for provide same user interface between GCC
and LLVM.

[llvm-objcopy] - Remove python invocations from 2 test cases.
It is possible to use yaml2obj to create sections with overlapping
sh_offset now. This patch does that.

[Clang] Pragma vectorize_width() implies vectorize(enable)
Specifying the vectorization width was supposed to implicitly enable
vectorization, except that it wasn't really doing this. It was only
setting the vectorize.width metadata, but not vectorize.enable.
This should fix PR27643.

[LoopUnroll] Use LoopSize+1 as threshold, to allow unrolling loops
matching LoopSize.
We use `< UP.Threshold` later on, so we should use LoopSize + 1, to
allow unrolling if the result won't exceed to loop size.
Fixes PR43305.
