The ARCv2 ISA provides the JLI instruction, which is two-byte instructions
that can be used to reduce code size in an application. To make use of it,
we provide two new function attributes 'jli_always' and 'jli_fixed' which
will force the compiler to call the indicated function using a jli_s
instruction. The compiler also generates the entries in the JLI table for
the case when we use 'jli_always' attribute. In the case of 'jli_fixed'
the compiler assumes a fixed position of the function into JLI
table. Thus, the user needs to provide an assembly file with the JLI table
for the final link. This is usefully when we want to have a table in ROM
and a second table in the RAM memory.
The jli instruction usage can be also forced without the need to annotate
the source code via '-mjli-always' command.

This was the original intent, as reflected in the long comment at the
start of names.cc, but I forgot to implement it.
Also, remove a leading ".0" from the final name. That could occur for
a method whose receiver type starts with 'u', as in that case we
prepend a space to the mangled name, to avoid confusion with the
Unicode mangling, and the space turns into ".0".
Also, if the Unicode encoding would cause the final to start with
"..u" or "..U", add a leading underscore.
Patch gotest to not get fooled by some names.
The result of these changes is that all symbols start with a letter or
an underscore.

Encode all external symbol names using only ASCII alphanumeric
characters, underscore, and dot. Use a scheme that can be reliably
demangled to a somewhat readable version as described in the long
comment in names.cc.
A minor cleanup discovered during this was that we were treating
function types as different if one had a NULL parameters_ field and
another has a non-NULL parameters_ field that has no parameters. This
worked because we mangled them slightly differently. We now mangle
them the same, so we treat them as equal, as we should anyhow.

PR target/68467 is libgcc failing to build for m68k-linux-gnu
configured for ColdFire.
Jeff has an analysis in the PR identifying the problem as resulting
from the callers of libcalls with 1-byte or 2-byte arguments wanting
to push just 1 or 2 bytes on the stack, while the libcall
implementations have the normal C ABI and expect 4-byte arguments.
For normal C functions, I believe the TARGET_PROMOTE_PROTOTYPES
definition would ensure such arguments get passed as 4-byte, but that
does not apply for libcalls.
This patch fixes the issue by defining TARGET_PROMOTE_FUNCTION_MODE
for m68k. The definition is conservative, only applying promotions in
the case of arguments to libcalls; otherwise it returns the unpromoted
type, which I believe matches what the default implementation of the
hook would have done on m68k.
I have tested that this fixes the libgcc build for ColdFire, and, in
conjunction with one glibc patch, this enables glibc to build cleanly
for ColdFire and to pass the compilation parts of the glibc testsuite
except for one test unrelated to this patch (while glibc and the
compilation parts of the testsuite continue to build OK for
non-ColdFire m68k, as expected). I have *not* run any GCC tests for
this patch, or any execution tests for m68k.

The failures in this PR were from forcing { dg-do run } even when
vect.exp chooses options that are incompatible with the runtime.
The default vect.exp behaviour is to execute when possible, so there's
no need for a dg-do at all.
The patch removes other unconditional { dg-do run }s too. Many of them
were already failing in the same way.
Also, the dg-do run condition in vect-reduc-or* seems unnecessary:
the test should run correctly whatever happens, and the scan tests
are already guarded properly.

This test fails on arm hardfloat targets because it sets an explicit -mfloat-abi=softfp.
The usual approach to setting the NEON options is to use dg-add-options arm_neon.
But in the lto tests we don't have that framework, we can only set them explicitly with dg-lto-options.
The solution is to remove the explicit -mfloat-abi=softfp and instead add an effective target check
for arm_neon_ok_no_float_abi that makes sure we only run this test if -mfpu=neon is enough to get NEON
without any -mfloat-abi options. In fact, this is what the comment above check_effective_target_arm_neon_ok_no_float_abi_nocache
recommends for lto tests.
That way on my hardfloat toolchain the test doesn't try to link the softfp binary against a hard-float runtime/test glue
and all is good. I've tested that the test is appropriately skipped when testing a --with-float=soft toolchain.
