The LIT test cases were migrated with the script provided by
Nikita Popov.
No manual changes were made. Committed without review since
no functional changes, after consultation with uweigand.
This patch fixes two deficiencies in current code that recognizes
the VLLEZ idiom:
- For the floating-point versions, we have ISel patterns that match
on a bitconvert as the top node. In more complex cases, that
bitconvert may already have been merged into something else.
Fix the patterns to match the inner nodes instead.
- For the 64-bit integer versions, depending on the surrounding code,
we may get either a DAG tree based on JOIN_DWORDS or one based on
INSERT_VECTOR_ELT. Use a PatFrags to simply match both variants.

This patch series adds support for the IBM z14 processor. This part includes:
- Basic support for the new processor and its features.
- Support for new instructions (except vector 32-bit float and 128-bit float).
- CodeGen for new instructions, including new LLVM intrinsics.
- Scheduler description for the new processor.
- Detection of z14 as host processor.
Support for the new 32-bit vector float and 128-bit vector float
instructions is provided by separate patches.
