[Bug ada/15835] New: label in inline assembler causes Gigi abort, Code=516

["jc at apinc dot org" <gcc-bugzilla at gcc dot gnu dot org>]

An assembler label inside System.Machine_Code.Asm make GNAT confused.
The label may be local (in the given testcase it is local) or non local.

This is not really an annoying bug so I give it a minor severity.
Futhermore this might be an incorrect use, but this is not written anywhere, and 
anyway shouldn't make GNAT abort without a good error message.

GCC version:
Reading specs from /usr/lib/gcc/i486-linux/3.4.0/specs
Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,
objc,ada,treelang --prefix=/usr --libexecdir=/usr/lib 
--with-gxx-include-dir=/usr/include/c++/3.4 --enable-shared --with-system-zlib 
--enable-nls --enable-threads=posix --without-included-gettext 
--program-suffix=-3.4 --enable-__cxa_atexit --enable-clocale=gnu 
--enable-libstdcxx-debug --enable-java-gc=boehm --enable-java-awt=gtk 
--disable-werror i486-linux
Thread model: posix
gcc version 3.4.0 (Debian 20040516)

Command line passed, see attached simple example:
$ gnatmake asm_label.adb 
gcc-3.4 -c asm_label.adb
