[Flang]Fix for changed code at the end of AllocaIP. (#92430)

Some of the OpenMP code can change the instruction pointed at by the
insertion point. This leads to an assert in the compiler about
BB->getParent() and IP->getParent() not matching.

The fix is to rebuild the insertionpoint from the block, rather than use
builder.restoreIP.

Also, move some of the alloca generation, rather than skipping back and
forth between insert points (and ensure all the allocas are done before
their users are created).

A simple test, mainly to ensure the minimal reproducer doesn't fail to
compile in the future is also added.

[RemoveDIs] Print IR with debug records by default (#91724)

This patch makes the final major change of the RemoveDIs project, changing the
default IR output from debug intrinsics to debug records.

[RemoveDIs] Print IR with debug records by default (#91724)

This patch makes the final major change of the RemoveDIs project, changing the
default IR output from debug intrinsics to debug records. This is expected to
break a large number of tests: every single one that tests for uses or
declarations of debug intrinsics and does not explicitly disable writing
records.

If this patch has broken your downstream tests (or upstream tests on a
configuration I wasn't able to run):
1. If you need to immediately unblock a build, pass
`--write-experimental-debuginfo=false` to LLVM's option processing for all
failing tests (remember to use `-mllvm` for clang/flang to forward arguments to
LLVM).
2. For most test failures, the changes are trivial and mechanical, enough that
they can be done by script; see the migration guide for a guide on how to do
this: https://llvm.org/docs/RemoveDIsDebugInfo.html#test-updates
3. If any tests fail for reasons other than FileCheck check lines that need
updating, such as assertion failures, that is most likely a real bug with this
patch and should be reported as such.

[Clang][OpenMP] Insert alloca for kernel args at function entry block instead of the launch point.

If an inlined kernel is called in a loop, the launch point alloca would
lead to increasing stack usage every time the kernel is invoked. This
could make the application run out of stack space and crash. This problem
is fixed by using the alloca insertion point while creating the alloca instruction.
