603a4ad499 Consider doloop IV in IVOPTs
For the targets supporting low-overhead loops, IVOPTs has to take care of
   the loops which will probably be transformed in RTL doloop optimization,
   to try to make selected IV candidate set optimal.  The process of doloop
   support includes:

   1) Analyze the current loop will be transformed to doloop or not, find and
      mark its compare type IV use as doloop use (iv_group field doloop_p), and
      set flag doloop_use_p of ivopts_data to notify subsequent processings on
      doloop.  See analyze_and_mark_doloop_use and its callees for the details.
      The target hook predict_doloop_p can be used for target specific checks.

   2) Add one doloop dedicated IV cand {(may_be_zero ? 1 : (niter + 1)), +, -1},
      set flag doloop_p of iv_cand, step cost is set as zero and no extra cost
      like biv.  For cost determination between doloop IV cand and IV use, the
      target hooks doloop_cost_for_generic and doloop_cost_for_address are
      provided to add on extra costs for generic type and address type IV use.
      Zero cost is assigned to the pair between doloop IV cand and doloop IV
      use, and bound zero is set for IV elimination.

   3) With the cost setting in step 2), the current cost model based IV
      selection algorithm will process as usual, pick up doloop dedicated IV if
      profitable.

a6fa2e83e9 gnatmake: Accept the `--sysroot=' GCC driver option
According to `gnatmake' documentation:

"Any uppercase or multi-character switch that is not a 'gnatmake' switch
is passed to 'gcc' (e.g., '-O', '-gnato,' etc.)"

however the `--sysroot=' switch is actually rejected:

gnatmake: invalid switch: --sysroot=...

likely because it is one of the very few GCC driver options that have a 
leading double dash and therefore we don't have a blanket fall-through 
for such switches that would satisfy what our documentation claims.

The option is actually shared between the compiler and the linker, so 
pass the switch to both build stages if requested, removing GNAT 
testsuite issues like:

gnatmake: invalid switch: --sysroot=.../sysroot
compiler exited with status 1
Executing on host: .../gcc/gnatclean -c -q -n ./abstract_with_anonymous_result   (timeout = 300)
spawn -ignore SIGHUP .../gcc/gnatclean -c -q -n ./abstract_with_anonymous_result
PASS: gnat.dg/abstract_with_anonymous_result.adb (test for excess errors)
UNRESOLVED: gnat.dg/abstract_with_anonymous_result.adb compilation failed to produce executable

in a test environment where `--with-build-sysroot=.../sysroot' has been 
used to build a cross-compiler.  Passing to the compilation stage only 
would lead to errors like:

.../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory
.../bin/riscv64-linux-gnu-ld: cannot find -lc
collect2: error: ld returned 1 exit status

a387d636cd compiler: suppress type descriptor generation for aliases
Change Named_object::get_backend to ignore aliases when creating type
    descriptors for types, to be consistent with
    Type::needs_specific_type_functions and the Specific_type_functions
    traversal class. For example, when compiling a package that creates an
    alias to an an externally defined type, e.g.
    
       import "foo"
       type MyFoo = foo.Foo
    
    it makes sense to skip the alias (not try to generate type specific
    functions for it) and let the normal mechanisms take care of the alias
    target, depending on whether the target is defined locally or defined
    elsewhere.
    
    Testcase for this problen can be found in CL 193261.
    
    Fixes golang/go#33866.

d694576e17 gotest: force test package to be imported first
When compiling the x_test package, force the test package to be
    imported first.  That ensures that we will see the types defined in
    the test package before the types defined in the non-test version of
    the package.  This matters if the types differ in some way, such as by
    adding a new method.
    
    This avoids a failure in internal/poll on Solaris, in which the test
    package adds a method to a type (FD.EOFError).  I think it was Solaris-
    specific because files are sorted in a different order by default.
    
    The go tool handles this kind of thing correctly, by rebuilding
    dependent packages.  This is just a hack sufficient to run the libgo
    testsuite without using the go tool.
