release call

findSafeStoreForStoreStrongContraction checks whether it's safe to move
the release call to the store by inspecting all instructions between the
two, but was ignoring retain instructions. This was causing objects to
be released and deallocated before they were retained.

This patch adds Pass1 of MIRADDFSDiscriminatorsPass before register

Block-Placement. This is still under --enable-fs-discrmininator

Existing linalg.conv2d is not well optimized for performance. Changed to a
version that is more aligned for optimziation. Include the corresponding

This also splits the conv and depthwise conv into separate implementations

    #include <istream>
    bool a(std::istream a) {

We can unbreak it by restoring the conversion to something-convertible-to-bool.

As noted, we might be able to restore the min/max patterns
with select folds, or we just wait for this to become easier
with canonicalization to min/max intrinsics.

When enable CSPGO for ThinLTO, there are profile cfg mismatch warnings that will cause lld-link errors (with /WX)
due to source changes (e.g. `#if` code runs for profile generation but not for profile use)
To disable it we have to use an internal "/mllvm:-no-pgo-warn-mismatch" option.
In contrast clang uses option ”-Wno-backend-plugin“ to avoid such warnings and gcc has an explicit "-Wno-coverage-mismatch" option.

Add "lto-pgo-warn-mismatch" option to lld COFF/ELF to help turn on/off the profile mismatch warnings explicitly when build with ThinLTO and CSPGO.

This patch should fix the use-after-free error that was brought up by
the LLDB ASAN Green Dragon bot.

This is caused because the `StringRef` object was acquired too early
before being use and by the underlying memory was modified which caused
it to point to null memory.

Fetching back the string reference close to its usage location should
fix the issue.

The constraint was checking that the type is not an LLVM structure or array
type, but was not checking that it is an LLVM-compatible type, making it accept
incorrect types. As a result, some LLVM dialect ops could process values that
are not compatible with the LLVM dialect leading to further issues with
conversions and translations that assume all values are LLVM-compatible. Make
LLVM_AnyNonAggregate only accept LLVM-compatible types.

Temporary files created by the offloading device toolchain are not removed
after compilation when using a two-step compilation. The offload-bundler uses a
different filename for the device binary than the `.o` file present in the
Job's input list. This is not listed as a temporary file so it is never
removed. This patch explicitly adds the device binary as a temporary file to
consume it. This fixes PR50336.

This test is specifying the lldb log channel via `ll""db` which only really works
because the command parser ends up parsing that as `lldb`. Just putting the
channel name in quotes is enough to avoid the lldb command substitution and
doesn't rely on this weird parser behaviour.
