The length in the .debug_addr unit header was calculated using the number
of elements in the addr_index_table. This is wrong because the entries in
the table are refcounted and only those with a refcount > 0 are actually
put in the index. Add a helper function count_index_addrs to get the
correct number of addresses in the index.

gcc/ChangeLog:

	* dwarf2out.c (count_index_addrs): New function.
	(dwarf2out_finish): Use count_index_addrs to calculate addrs_length.

When the AESE,AESD and AESMC, AESMC instructions are generated through the appropriate arm_neon.h intrinsics
we really want to keep them together when the AESE feeds into an AESMC and fusion is supported by the target CPU.
We have macro-fusion hooks and scheduling model forwarding paths defined to facilitate that.
It is, however, not always enough.

This patch adds another mechanism for doing that.
When we can detect during combine that the required dependency is exists (AESE -> AESMC, AESD -> AESIMC)
just keep them together with a combine pattern throughout the rest of compilation.
We won't ever want to split them.

The testcases generate 4 AESE(D) instructions in a block followed by 4 AES(I)MC instructions that
consume the corresponding results and it also adds a bunch of computations in-between so that the
AESE and AESMC instructions are not trivially back-to-back, thus exercising the compiler's ability
to bring them together.

With this patch all 4 pairs are fused whereas before a couple of fusions would be missed due to intervening
arithmetic and memory instructions.

[arm] PR target/85733 Restore be8 linking behaviour for ARMv6-M and products deriving from its capabilities

My patch last year to automate passing the be8 flag to the linker had
a nasty flaw in that I forgot entirely that the ARMv6-M architecture
did not derive its capabilities directly from the ARMv6 capability
list, but was a new group of capabilities (since it needs to leave out
the ARM -- notm -- feature bit).  The feature list defined was thus
missing the be8 bit.  Furthermore, any product derived from that
feature group consequently lacked the be8 feature as well and this
included all ARMv7 and ARMv8 parts.

The fix is embarrassingly simple...
