[APFloat] Add E4M3B11FNUZ
X. Sun et al. (https://dl.acm.org/doi/10.5555/3454287.3454728) published
a paper showing that an FP format with 4 bits of exponent, 3 bits of
significand and an exponent bias of 11 would work quite well for ML
applications.
Google hardware supports a variant of this format where 0x80 is used to
represent NaN, as in the Float8E4M3FNUZ format. Just like the
Float8E4M3FNUZ format, this format does not support -0 and values which
would map to it will become +0.
This format is proposed for inclusion in OpenXLA's StableHLO dialect: https://github.com/openxla/stablehlo/pull/1308
As part of inclusion in that dialect, APFloat needs to know how to
handle this format.

[NVPTX] Introduce attribute to mark kernels without a language mode
We may want to be able to mark certain regions as kernels even without
being in an accepted CUDA or OpenCL language mode. This patch introduces
a new attribute limited to `nvptx` targets called `nvptx_kernel` which
will perform the same metadata action as the existing CUDA ones. This
closely mimics the behaviour of the `amdgpu_kernel` attribute. This
allows for making executable NVPTX device images without using an
existing offloading language model.
I was unsure how to do this, I could potentially re-use all the CUDA
attributes and just replace the `CUDA` language requirement with an
`NVPTX` architecture requirement. Also I don't know if I should add more
than just this attribute.

[BOLT] Don't use section relocations when computing hash for data from other section
When computing symbol hashes in BinarySection::hash, we try to find relocations
in the section which reference the passed BinaryData. We do so by doing
lower_bound on data begin offset and upper_bound on data end offset. Since
offsets are relative to the current section, if it is a data from the previous
section, we get underflow when computing offset and lower_bound returns
Relocations.end(). If this data also ends where current section begins,
upper_bound on zero offset will return some valid iterator if we have any
relocations after the first byte. Then we'll try to iterate from lower_bound to
upper_bound, since they're not equal, which in that case means we'll dereference
Relocations.end(), increment it, and try to do so until we reach the second
valid iterator. Of course we reach segfault earlier. In this patch we stop BOLT
from searching relocations for symbols outside of the current section.
