[BranchFolding] Allow hoisting to block with a single conditional branch.
Summary:
The BranchFolding pass is currently missing opportunities to hoist
common code if the hoisted-to block contains a single conditional branch
that has register uses. This occurs somewhat frequently on AArch64 with
CBZ/TBZ opcodes.
This change also eliminates some code differences when debug info is
present since the presence of e.g. DBG_VALUE instructions in the
hoisted-to block can enable hoisting that wouldn't have occurred without
them.

Although launching a process for debugging is the most important kind of

breaking layering). Instead of assuming a particular exit callback, I

up the two call sites which did not set the callback already).

[CodeGen] Disable aggressive structor optimizations at -O0
Summary:
Removing the full structor and replacing all usages with the base one
can degrade debug quality as it will leave the debugger unable to locate
the full object structor. This is apparent when evaluating an expression
in the debugger which requires constructing an object of class which has
had this optimization applied to it. When compiling the expression, we
pretend that the class and its methods have been defined in another
compilation unit, so the expression compiler assumes the structor
definition must be available. This didn't use to be the case for
structors with internal linkage. Less aggressive optimizations like
emitting the full structor as an alias remain in place, as they do not
cause the structor symbol to disappear completely.
This improves debug quality on non-darwin platforms (darwin does not
have -mconstructor-aliases on by default, so it is spared these
problems) and enable us to remove some workarounds from LLDB which attempt to
mitigate this issue.

This change allows for handling the in-memory data associated with the

This for example allows users to stream the data of the FDR logging

instead of saving them to local files.
We introduce an FDR-specific flag, for "no_file_flush" which lets the
flushing logic skip opening/writing to files.
This option can be defaulted to `true` when building the compiler-rt
XRay runtime through the `XRAY_FDR_OPTIONS` preprocessor macro.

This pass does pass all the unit tests, however clang
no longer generates code that looks like the unit test

Clear converters map after X86 Domain Reassignment to avoid crashes
Summary:
As reported in PR37264, in some cases the X86 Domain Reassignment
`runOnMachineFunction()` is called twice. Because it only deletes the
`.second` members of its `InstrConverterBaseMap`, and does not clean up
the map itself, this can lead to double frees and crashes.
Use `DeleteContainerSeconds()` instead, so the `Converters` map can
safely be reinitialized and its members re-deleted for each X86 Domain
Reassignment pass.

Summary:
Currently the order of blocks returned by `IDF::calculate` can be
non-deterministic. This was discovered in several attempts to enable
SSAUpdaterBulk for JumpThreading (which led to miscompare in bootstrap between
stage 3 and stage4). Originally, the blocks were put into a priority queue with
a depth level as their key, and this patch adds a DFSIn number as a second key
to specify a deterministic order across blocks from one level.
The solution was suggested by Daniel Berlin.
