GlobalISel: Implement widenScalar for G_INSERT_VECTOR_ELT

[AMDGPU] Fixed asan failure in SIFoldOperands
Both tryFoldOMod() and tryFoldClamp() remove original instruction, so
the check MI.modifiesRegister() may use a deleted MI.

Revert "[ARM] Uses "Sun Style" syntax for section switching"
This reverts commit 03de2f84fc4acf06c719cd007b5459c9d4d0a20c.

    Add the ability to pass extra args to a Python breakpoint callback.
    For example, it is pretty easy to write a breakpoint command that
implements "stop when my caller is Foo", and
   it is pretty easy to write a breakpoint command that implements "stop
when my caller is Bar". But there's no
   way to write a generic "stop when my caller is..." function, and then
specify the caller when you add the
   command to a breakpoint.
    With this patch, you can pass this data in a SBStructuredData
dictionary. That will get stored in
   the PythonCommandBaton for the breakpoint, and passed to the
implementation function (if it has the right
   signature) when the breakpoint is hit. Then in lldb, you can say:
    (lldb) break com add -F caller_is -k caller_name -v Foo
    More generally this will allow us to write reusable Python
breakpoint commands.
