[lldb][docs] Fix table formatting in bytecode docs
Me adding extra backticks caused all these to be misaligned.
This didn't show up on the docs buildbot but did error in
CI on a later PR of mine.
[lldb][docs] Describe how to check enabled features (#171468)
This makes use of `version -v` added by #170772,
along with fallback methods for LLDB prior to 22.
1. version --verbose (won't work prior to 22)
2. Scripting to call GetBuildConfiguration (won't work if you don't have
a scripting language
3. readelf/other platform's equivalent utility
readelf is recommended for Linux due to security concerns with ldd.
https://man7.org/linux/man-pages/man1/ldd.1.html
"some versions of ldd may attempt to obtain the
dependency information by attempting to directly
execute the program"
The drawback to that is it doesn't show dependencies of dependencies, so
I've noted that. People can use ldd if they trust the binary, but I've
made it clear how to avoid that and why you should avoid it.
Add sys/_align.h replacing machine/_align.h
Define _ALIGNBYTES using sizeof(void *) (no functional change on any
existing architecture) which will allow it to work with CHERI were we
must align things up to capability alignment.
In _ALIGN, replace integer manipulation which does not preserve pointer
provenance with a type and provenance preserving builtin. This requires
modest changes in code which assumes _ALIGN returns an integer, but
those are relatively rare.

get*ent: be consistant about _ALIGN(p) - p
Add an nscache specific inline function to calculate the misalignment
rather than adding and subtracting _ALIGN(p) and p which can take the
buffer far out of bound (undefined behavior in C and unsupported on
CHERI).

[OpenMP][MLIR] Hoist static `alloca`s emitted by private `init` regions to the allocation IP of the construct
Having more than 1 descritpr (allocatable or array) on the same `private` clause triggers a runtime crash on GPUs at the moment.
For SPMD kernels, the issue happens because the initialization logic includes:
* Allocating a number of temporary structs (these are emitted by flang when `fir` is lowered to `mlir.llvm`).
* There is a conditional branch that determines whether we will allocate storage for the descriptor and initialize array bounds from the original descriptor or whether we will initialize the private descriptor to null.
Because of these 2 things, temp allocations needed for descriptors beyond the 1st one are preceded by branching which causes the observed the runtime crash.
This PR solves this issue by hoisting these static `alloca`s instructions to the suitable allca IP of the parent construct.

Forgot to link GPU lib and shared lib build failed.
[SDAG] Remove most non-canonical libcall handing (#171288)
This is a followup to https://github.com/llvm/llvm-project/pull/171114,
removing the handling for most libcalls that are already canonicalized
to intrinsics in the middle-end. The only remaining one is fabs, which
has more test coverage than the others.
[SelectOptimize] Fix incorrect -1 immediate for large integers (#170860)
This was creating a -1 with zero extension, while it needs to use sign
extension.
[OpenCL] Add cl_khr_subgroup_named_barrier and cl_intel_required_subgroup_size to OpenCLExtensions.def (#171433)
Fix typo cl_intel_bfloat16_conversion.
Add test for checking intel extension functions.
[lldb-dap] Increase DAP default timeout (#170890)
DAP tests easily timeout when the computer is under-load.
This is easily noticeable if you run the test in a loop a compile llvm.
or running the test on slower CI/machines.
This affects mostly the `DAP_launch`, `DAP_attach`,
`DAP_restart_console` and occasionally `DAP_output` tests.
Would lead in the direction of enabling some of the test on windows.

[mlir][amdgpu] Add common gpu mem space conversions to `convert-amdgpu-to-rocdl` (#171543)
Without it `convert-amdgpu-to-rocdl` will fail to convert
`amdgpu.gather_to_lds` with `#gpu.address_space<workgroup>` mem space.
