[AArch64] Handle literal pools for functions > 1 MiB in size.

This patch fixes the issue in PR63304 where we have
functions that are > 1MiB. The idea is to use adrp / ldr or adrp / add
instructions to address the literal pools under the use of a command line
option. I would like to turn this on by default on trunk but keep this
disabled by default for the release branches in order to get some
serious testing for this feature while it bakes on trunk.

As a follow-up I would like to try and see if estimate_num_insns or
something else can give us a heuristic to turn this on for "large" functions.
After all the number of incidences of this are quite low in real life,
so may be we should look to restrict this use as much as possible on the
grounds that this code generation implies an extra integer register for
addressing for every floating point and vector constant and I don't think
that's great in code that already may have high register pressure.

Tested on aarch64-none-elf with no regressions. A previous
version was bootstrapped and regression tested.

Applied to trunk.

[Patch PR target/67366 1/2] [ARM] - Add movmisalignhi / si patterns

This adds movmisalignhi and movmisalignsi expanders when unaligned
access is allowed by the architecture. This allows the mid-end
to expand to misaligned loads and stored.

Compared code generated for the Linux kernel and
it changes code generation for a handful of files all for the better
basically by reducing the stack usage.

Make tree_expr_nonnegative_warnv_p recurse into SSA names

The upcoming patch to move sqrt and cbrt simplifications to match.pd
caused a regression because the (abs @0)->@0 simplification didn't
trigger for:

        (abs (convert (abs X)))

The simplification is based on tree_expr_nonnegative_p, which at
the moment just gives up if it sees an SSA_NAME.

This patch makes tree_expr_nonnegative_p recurse into SSA name
definitions, but limits the depth of recursion to a small number
for the reason mentioned in the comment (adapted from an existing
comment in gimple_val_nonnegative_real_p).  The patch reuses code
in tree-vrp.c, moving it to gimple-fold.c.  It also replaces calls
to gimple_val_nonnegative_real_p with calls to tree_expr_nonnegative_p.

A knock-on effect is that we can now prove _i_589 < 0 is false in
sequences like:

      i_1917 = ASSERT_EXPR <i_1075, i_1075 == 0>;
      _i_589 = (const int) i_1917;
      _i_1507 = ASSERT_EXPR <_i_589, _i_589 < 0>;

This defeats an assert in tree-vrp.c that ASSERT_EXPR conditions
are never known to be false.  Previously the assert only ever used
local knowledge and so would be limited to cases like x != x for
integer x.  Now that we use global knowledge it's possible to prove
the assertion condition is false in blocks that are in practice
unreachable.  The patch therefore removes the assert.

Bootstrapped & regression-tested on x86_64-linux-gnu.  I didn't write
a specific test because this is already covered by the testsuite if
the follow-on patch is also applied.

gather bbs and conditions in a single walk through dominators

Clean up the function to build scop's basic blocks and the function
that gathers the conditions under which a basic block is executed.  We remove
one traversal of the dominator tree.

This refactoring was triggered by the need of a vec<bb> of all the basic blocks
in a region.  We will use that vector in a patch that removes the out-of-ssa
translation of scalar dependences: we will iterate through the basic blocks of a
region to record scalar dependences crossing bbs or going out of the region.

The patch passes bootstrap and regtest on x86_64-linux.

compiler: Record each import as a distinct alias.

    This patch introduces the Package_alias class which is a
    finer representation of the different between a package and the
    aliases it is imported under.  Each alias keeps track of the location
    of its import statement and how many times that alias has been used.
    This allows the gofrontend to report when a specific import has not
