[patch] Do not call output_constant from the front end

Hello,

The Java front end emits assembly from class.c:emit_register_classes()
to fill the .jcr section. This is not something a front end ought to
be doing. Things to write out to the assembler output file should go
through the varpool/varasm mechanism. The attached patch makes
emit_register_classes build a constructor for the .jcr section, and
stops it calling output_constant.

The patch passes build+testing on powerpc64-unknown-linux-gnu.

With this patch a variable named "_Jv_CLS" is written out. The
assembly before and after the patch is the same, except for the
variable name. I want to write out a nameless variable but I don't
know how. Help welcome.

Ciao!
Steven
