Cleanup coro-inline.ll

Following up with the comments in D92706.
- Use -passes instead of -enable-new-pm
- CoroEarly should happen before AlwaysInliner, adjust it.
- Remove some unnecessary barriers (still kept one)
- Cleanup unnecessary debug info

[ARM] Match dual lane vmovs from insert_vector_elt

MVE has a dual lane vector move instruction, capable of moving two
general purpose registers into lanes of a vector register. They look
like one of:
  vmov q0[2], q0[0], r2, r0
  vmov q0[3], q0[1], r3, r1
They only accept these lane indices though (and only insert into an
i32), either moving lanes 1 and 3, or 0 and 2.

This patch adds some tablegen patterns for them, selecting from vector
inserts elements. Because the insert_elements are know to be
canonicalized to ascending order there are several patterns that we need
to select. These lane indices are:

3 2 1 0    -> vmovqrr 31; vmovqrr 20
3 2 1      -> vmovqrr 31; vmov 2
3 1        -> vmovqrr 31
2 1 0      -> vmovqrr 20; vmov 1
2 0        -> vmovqrr 20

With the top one being the most common. All other potential patterns of
lane indices will be matched by a combination of these and the
individual vmov pattern already present. This does mean that we are
selecting several machine instructions at once due to the need to
re-arrange the inserts, but in this case there is nothing else that will
attempt to match an insert_vector_elt node.

This is a recommit of 6cc3d80a84884a79967fffa4596c14001b8ba8a3 after
fixing the backward instruction definitions.

[mlir][Linlag] Reflow Linalg.md - NFC

Markdown formatting seems to now be available, reflowing the doc without changing any content.

[ELF] Rename R_TLS to R_TPREL and R_NEG_TLS to R_TPREL_NEG. NFC

The scope of R_TLS (TP offset relocation types (TPREL/TPOFF) used for the
local-exec TLS model) is actually narrower than its name may imply. R_TLS_NEG
is only used by Solaris R_386_TLS_LE_32.

Rename them so that they will be less confusing.
