[AMDGPU] Add an option to disable manual ctor / dtor lowering
Currently AMDGPU offers extra ctor / dtor lowering by emitting a kernel
that can be called. It's possible to handle ctors and dtors using the
standard method as shown in D149340's commit message. In which case we
on't need these extra kernels as they won't be called. This patch simply
adds a way to conditionally turn off this handling if we do not want to
get extra kernels in the output.
Unrelated, but we could convert this handling to an ODR function that simply
calls the code in D149340 constructed via LLVM-IR. That would handle priority
correctly and would then be correct if not run in LTO mode.

This patch analyzes AVX512 instructions for full vector width folded loads from the constant pool and attempts to determine if it can be replaced with a smaller broadcast folded variant. Typically the broadcast opportunities were missed by type-width mismatches or mulituse limitations which have been removed in later passes.
As well as introducing broadcast fold tables (which can hopefully be extended/automated in the future), this also handles mismatches in the AND/ANDN/OR/XOR/TERNLOG type-widths, catching additional missed opportunities.
This is patch is pulled from the ongoing work based on D150143, but without removing the existing DAG constant broadcast lowering code - this patch is currently a late stage cleanup only.

When inner forall bound computations do not depend on previous
forall indices, they can be hoisted.
This is possible because:
- bound computation are required to be pure (so evaluating them only
once is possible).
- If the bound computation depends on a value previously assigned, the
forall scheduling analysis created different run for it: the
assignment impacting the bounds value is not part of the current loop
nest.
The reason this optimization is done at that point and not as part of
generic loop hoisting optimization is that having the all the loop

storages. The number of iteration can be pre-computed and used as the
extent for the temporary.

This patch restores the pre-D145586 behavior

have a 32 VGPRs threshold, but only if the function
is not marked with "alwaysinline".
A good number of AMDGPU code makes uses of

This is a retry of https://reviews.llvm.org/D114583, which was backed
out for regressions.
Clang Format is detecting a nested scope followed by another open brace
as a braced initializer list due to incorrectly thinking it's matching a
braced initializer at the end of a constructor initializer list which is
followed by the body open brace.
Unfortunately, UnwrappedLineParser isn't doing a very detailed parse, so
it's not super straightforward to distinguish these cases given the
current structure of calculateBraceTypes. My current hypothesis is that
these can be disambiguated by looking at the token preceding the
l_brace, as initializer list parameters will be preceded by an
identifier, but a scope block generally will not (barring the MACRO
wildcard).
To this end, I am adding tracking of the previous token to the LBraceStack
to help scope this particular case.

[CodeGen] Fix incorrect usage of MCPhysReg for diff list elements
The lists contain differences between register numbers, not the register
numbers themselves. Since a difference can also be negative, this also
changes its type to signed.
Changing the type to signed exposed a "bug". For AMDGPU, which has many
registers, the first element of a sequence could be as big as ~45k.
The value does not fit into int16_t, but fits into uint16_t. The bug
didn't show up because of unsigned wrapping and truncation of the Val
field in the advance() method.
To fix the issue, I changed the way regunit difflists are encoded. The
4-bit 'scale' field of MCRegisterDesc::RegUnit was replaced by 12-bit
number of the first regunit, and the first element of each of the lists
was removed. The higher 20 bits of RegUnit field contain the initial
offset into DiffLists array.
AMDGPU has 1'409 regunits (2^12 = 4'096), and the biggest offset is
80'041 (2^20 = 1'048'576). That is, there is enough room.
Changing the encoding method also resulted in a smaller array size, the
numbers are below (I omitted targets with less than 100 elements).
```
AMDGPU | 80052 | 78741 | -1,6%
RISCV | 6498 | 6297 | -3,1%
ARM | 4181 | 3966 | -5,1%
