During active replay, the ::Initialize call is replayed like any other
SB API call and the return value is ignored. Since we can't intercept
this, we terminate here before the uninitialized debugger inevitably
crashes.

I found a few cases where entries in the debug_line for a specific line of code have invalid entries (the address is outside of a code section or no section at all) and also valid entries. When this happens lldb might not set the breakpoint because the first line entry it will find in the line table might be the invalid one and since it's range is "invalid" no location is resolved. To get around this I changed the way we parse the line sequences to ignore those starting at an address under the first code segment.
Greg suggested to implement it this way so we don't need to check all sections for every line sequence.

Add a calling convention called amdgpu_gfx for real function calls
within graphics shaders. For the moment, this uses the same calling
convention as other calls in amdgpu, with registers excluded for return
address, stack pointer and stack buffer descriptor.

This to help review the impact of https://reviews.llvm.org/D89952 which
allows targets to fine tune what SelectionDAG does when vector CTPOP is
not legal.
This patch make the outliner emit CFI instructions in a few more
places:
* after LR is restored, but before the return in an outlined
function
* around save/restore of LR to/from a register at calls to outlined
functions
* around save/restore of LR to/from the stack at calls to outlined
functions
The latter two only when the function does NOT spill LR. If the
function spills LR, then outliner generated saves/restores around
calls are not considered interesting for unwinding the frame.

There were cases where a VCMP and a VPST were merged even if the VCMP
didn't have the same defs of its operands as the VPST. This is fixed by
adding RDA checks for the defs. This however gave rise to cases where
the new VPST created would precede the un-merged VCMP and so would fail
a predicate mask assertion since the VCMP wasn't predicated. This was
solved by converting the VCMP to a VPT instead of inserting the new
VPST.

The legalization did not forward the listener which prevents dynamic
legalization and prevents rollbacks. This handled that and then changed
the associated pass to support all other std ops to support partial
conversion.
Previously, this lowering was failing, but due to the
initial bug, the op's modifications were not reverted, and thus the
pattern matching succeeded.

Introduce struct FlattenInfo to group some of the bookkeeping. Besides this
being a bit of a clean-up, it is a prep step for next additions (D90640). I
could take things a bit further, but thought this was a good first step also
not to make this change too large.

In C++ with -Werror=comment, multiline comments are not allowed.
clang-format could accidentally introduce multiline comments when reflowing.
This adapts clang-format to not introduce multiline comments by not allowing a
break after `\`. Note that this does not apply to comment lines that already are
multiline comments, such as comments in macros.

The altera kernel name restriction check finds kernel files and include
directives whose filename is "kernel.cl", "Verilog.cl", or "VHDL.cl".
Such kernel file names cause the Altera Offline Compiler to generate
intermediate design files that have the same names as certain internal
files, which leads to a compilation error.
As per the "Guidelines for Naming the Kernel" section in the "Intel FPGA
SDK for OpenCL Pro Edition: Programming Guide."
This reverts the reversion from 43a38a6523.
Enumerating elements in these classes is necessary to enable custom

Operations in a MLIR have a dictionary of attributes attached. Expose
those to Python bindings through a pseudo-container that can be indexed
either by attribute name, producing a PyAttribute, or by a contiguous
