[lldb/SWIG] Undo incorrect substitution
The Python directory for the script interpreter is still capitalized.
The file was modifiedlldb/bindings/python.swig

[SystemZ] Fix matching another pattern for nxgrk (PR44496)
SystemZDAGToDAGISel::Select will attempt to split logical instruction 
with a large immediate constant.  This must not happen if the result 
matches one of the z15 combined operations, so the code checks for 
those.  However, one of them was missed, causing invalid code to be
generated in the test case for PR44496.

[x86] add tests for 2-way splat copy; NFC
Based on code in PR42024: https://bugs.llvm.org/show_bug.cgi?id=42024

[Support][NFC] Add an explicit unit test for Process::getPageSize()
It turns out that it was only tested indirectly. For now test only on
Linux X86-64 and aarch64.

[TargetLowering][X86] TeachSimplifyDemandedBits to handle cases where
only the sign bit is demanded from a SETCC and can be passed through
If we're doing a compare that only tests the sign bit and only the sign
bit is demanded, we can just bypass the node. This removes one of the
blend dependencies in our v2i64->v2f32 uint_to_fp codegen on pre-sse4.2
targets.
