Ahmed Bougacha dff57a6143 [AArch64] Prefer DUP/MOV ("CPY") to INS for vector_extract.
This avoids a partial false dependency on the previous content of
the upper lanes of the destination vector register.

Ahmed Bougacha aab9677f65 [AArch64] Add a few more DUP testcases. NFC.
Also, don't lie about testing index 0.

Ahmed Bougacha 77b76542eb [AArch64] Robustize neon-scalar-copy.ll tests. NFC.
Some of those didn't even have run lines: they were removed
inadvertently during the Great Merge of 2014.

They used to check for DUPs, but now we go through W-regs?
Filed PR22418 for that potential regression.

For now, just make the tests explicit, so we now where we stand.

Tim Northover 3b0846e8f7 AArch64/ARM64: move ARM64 into AArch64's place
This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.

"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.

This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.

Tim Northover cc08e1fe1b AArch64/ARM64: remove AArch64 from tree prior to renaming ARM64.
I'm doing this in two phases for a better "git blame" record. This
commit removes the previous AArch64 backend and redirects all
functionality to ARM64. It also deduplicates test-lines and removes
orphaned AArch64 tests.

The next step will be "git mv ARM64 AArch64" and rewire most of the
tests.

Hopefully LLVM is still functional, though it would be even better if
no-one ever had to care because the rename happens straight
afterwards.

Kevin Qin e4ddaa1bd5 Fix Incorrect CHECK message [0-31]+ in test case.
In regular expression, [0-31]+ equals to [0-3]+, not the number from
0 to 31. So change it to [0-9]+.
