3f30a27491 libiberty: Update D symbol demangling for latest ABI spec.
Some small improvements and clarifications have been done in the D ABI
specification to remove all ambiguities found in the current grammar,
this implementation now more closely resembles the spec, whilst
maintaining compatibility with the old ABI.

Three new rules have been added to the ABI.

1. Back references using 'Q', analogous to C++ substitutions, compresses
   repeated identifiers, types, and template symbol and value parameters.

2. Template aliases to externally mangled symbols are prefixed with 'X'.
   This includes any symbol that isn't extern(D), or has its name
   overriden with pragma(mangle).  This fixes an ambiguity where it was
   not clear whether 'V' was an encoded calling convention, or the next
   template value parameter.

3. Alias parameters, templates, and tuple symbols no longer encode the
   symbol length of its subpart.  Tuples are now terminated with 'Z'.
   This fixes another ambiguity where the first character of the mangled
   name can be a digit as well, so the demangler had to figure out where
   to split the two adjacent numbers by trying out each combination.

libiberty/ChangeLog:

	* d-demangle.c (enum dlang_symbol_kinds): Remove enum.
	(struct dlang_info): New struct
	(dlang_decode_backref): New function.
	(dlang_backref): New function.
	(dlang_symbol_backref): New function.
	(dlang_type_backref): New function.
	(dlang_symbol_name_p): New function.
	(dlang_function_type_noreturn): New function.
	(dlang_function_type): Add 'info' parameter.  Decode function type
	with dlang_function_type_noreturn.
	(dlang_function_args): Add 'info' parameter.
	(dlang_type): Add 'info' parameter.  Handle back referenced types.
	(dlang_identifier): Replace 'kind' parameter with 'info'.  Handle back
	referenced symbols.  Split off decoding of plain identifiers to...
	(dlang_lname): ...here.
	(dlang_parse_mangle): Replace 'kind' parameter with 'info'.  Decode
	function type and return with dlang_type.
	(dlang_parse_qualified): Replace 'kind' parameter with 'info', add
	'suffix_modifier' parameter.  Decode function type with
	dlang_function_type_noreturn.
	(dlang_parse_tuple): Add 'info' parameter.
	(dlang_template_symbol_param): New function.
	(dlang_template_args): Add 'info' parameter.  Decode symbol parameter
	with dlang_template_symbol_param.  Handle back referenced values, and
	externally mangled parameters.
	(dlang_parse_template): Add 'info' parameter.
	(dlang_demangle_init_info): New function.
	(dlang_demangle): Initialize and pass 'info' parameter.
	* testsuite/d-demangle-expected: Add new tests.

eedc73a224 Check whether -fcf-protection=none -Wl,-z,ibt,-z,shstk work first
GCC_CET_HOST_FLAGS uses -Wl,-z,ibt,-z,shstk to check if Linux/x86 host
has Intel CET enabled by introducing an Intel CET violation on purpose.
To avoid false positive, check whether -Wl,-z,ibt,-z,shstk works first.
-fcf-protection=none is added to avoid false negative when -fcf-protection
is enabled by default.

8fc8bf801e Enable Intel CET in liblto_plugin.so on Intel CET enabled host
Since ld is Intel CET enabled on Intel CET enabled host, dlopen fails on
liblto_plugin.so if it isn't Intel CET enabled.  Add GCC_CET_HOST_FLAGS
to cet.m4, use it in libiberty and lto-plugin to always enable Intel
CET in liblto_plugin.so on Intel CET enabled host.

On Linux/x86 host, enable Intel CET by default if assembler and compiler
support Intel CET so that the generated liblto_plugin.so can be used on
both CET and non-CET machines.  It is an error to disable Intel CET in
liblto_plugin.so on Intel CET enabled host.

into the final objects as in the following example:

[egeyar@localhost lto]$ gcc -flto -O2 demo2.c -c -g --record-gcc-command-line -DFORTIFY=2
[egeyar@localhost lto]$ gcc demo.o demo2.o -o a.out
[egeyar@localhost lto]$ readelf -p .GCC.command.line a.out

String dump of section '.GCC.command.line':
  [     0]  10.0.1 20200227 (experimental) : gcc -flto -O3 demo.c -c -g --record-gcc-command-line

02ce382cd3 Use a non-empty test program to test ability to link.
On bare-metal targets, I/O support is typically provided by a BSP and
requires a linker script and/or hosting library to be specified on the
linker command line.  Linking an empty program with the default linker
script may succeed, however, which confuses libstdc++ configuration
when programs that probe for the presence of various I/O features fail
with link errors.
