DWARF: move pessimistic DWARF version checks for imported entities

A check in dwarf2out_imported_module_or_decl prevents
DW_TAG_imported_module from being emitted as it was introduced in the
DWARFv3 standard. However, this also prevents valid strict DWARFv2
constructs such as DW_TAG_imported_declaration from being emitted in
dwarf2out_imported_module_or_decl_1.

The latter already protects the emission of newer DWARF tags with
appropriate checks, so the one in the former is redundant and
pessimistic.  This function is already called from places like
process_scope_var, which are not protected anyway.

This patch moves the check in dwarf2out_imported_module_or_decl so that
in strict DWARFv2 mode, tags like DW_TAG_imported_declaration are
emitted while DW_TAG_imported_module are not.

    The Go runtime package is picking up C macros from runtime_sysinfo.go
    and then re-exporting them to runtime.inc.  This can cause name
    conflicts.  Change the Makefile so that we only put the macros we need
    into runtime.inc.  These are the constants that are actually defined by
    Go code, not runtime_sysinfo.go.  There are only a few, so we can
    pattern match.

    This is an additional hack on runtime.inc.  The long term goal is to

    a few hacks seem acceptable.

Fix failing gcc.target/avr/torture/builtins_error.c

The compiler defaults to thin LTO objects if built with linker plugin
support, and in that case, the error expected by the testcase appears
only at link time, if at all. Forcing fat LTO object file creation
generates the error consistently at compile time, as expected.

runtime: copy internal locking code from Go 1.7 runtime

    Remove the old locking code written in C.

    Add a shell script mkrsysinfo.sh to generate the runtime_sysinfo.go
    file, so that we can get Go copies of the system time structures and
    other types.

    Tweak the compiler so that when compiling the runtime package the
    address operator does not cause local variables to escape.  When the gc
    compiler compiles the runtime, an escaping local variable is treated as
    an error.  We should implement that, instead of this change, when escape
    analysis is turned on.

    Tweak the compiler so that the generated C header does not include names
    that start with an underscore followed by a non-upper-case letter,
    except for the special cases of _defer and _panic.  Otherwise we
    translate C types to Go in runtime_sysinfo.go and then generate those Go
    types back as C types in runtime.inc, which is useless and painful for
    the C code.

    Change entersyscall and friends to take a dummy argument, as the gc
    versions do, to simplify calls from the shared code.

[Patch] Remove all uses of TARGET_FLT_EVAL_METHOD_NON_DEFAULT and poison it

I'm going to hookize TARGET_FLT_EVAL_METHOD, so the current definition
of TARGET_FLT_EVAL_METHOD_NON_DEFAULT will stop working.

The relaxation enabled by TARGET_FLT_METHOD_NON_DEFAULT isn't portable,
and keeping it in place is tricky, so this patch removes it, and poisons
TARGET_FLT_EVAL_METHOD_NON_DEFAULT in system.h to prevent future use.

* defaults.h (TARGET_FLT_EVAL_METHOD_NON_DEFAULT): Remove.
* system.h (TARGET_FLT_EVAL_METHOD_NON_DEFAULT): Poison.
