This patch generalizes the formation of LDP/STP that require a base register.
In AArch64, LDP/STP instructions have different sized immediate offsets than
normal LDR/STR instructions. This part of the backend attempts to spot groups
of four LDR/STR instructions that can be turned into LDP/STP instructions by
using a base register.
Previously, we would only accept address pairs that were ordered in ascending
or descending order, and only strictly sequential loads/stores. In fact, the
instructions that we generate from this should be able to consider any order
of loads or stores (provided that they can be re-ordered). They should also be
able to accept non-sequential loads and stores provided that the two pairs of
addresses are amenable to pairing. The current code is also overly restrictive
on the range of addresses that are accepted, as LDP/STP instructions may take
negative offsets as well as positive ones.
This patch improves that by allowing us to accept all orders of loads/stores
that are valid, and extending the range that the LDP/STP addresses can reach.

This patch fixes a memory leak bug. In particular, in a loop of the form "for X
of ...", with a type that has the Iterable aspect specified, if the result of
the Element function is returned on the secondary stack (e.g. the result
subtype has caller-unknown size), then memory for the secondary stack could
leak.

gcc/ada/
* exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
We need to analyze it as part of analyzing the block, so that if the
call to Element that initializes Elmt_Decl returns on the secondary
stack, the block will ss_mark/ss_release. This block is inside the
loop; we don't want to leak memory until the loop exits. The purpose
of analyzing Elmt_Decl first was to catch the error of modifying it,
which is illegal because it's a loop parameter. The above causes us to
miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
it on the Element entity, so we end up with an E_Variable node with the
flag set.
* einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
