[fortran,patch] Fix simplification of expressions containing constant arrays

Subject: [fortran,patch] Fix simplification of expressions containing constant arrays

This patch fixes PR33288: when we simplify an expression like (/1,2/)
+ 1 that contains an array constructor, some elements can be arrays
themselves, like in (/1,2,(/3/)/), in which case the simplification
routine went wrong. In fact, when we encounter this case, we simply
need to call the simplification routine recursively and all is fine.
This fixes unary and binary operators (where at least one of the
arguments is an array constructor).

Bootstrapped and regtested on x86_64-linux (-m64 and -m32), comes with
a testcase. OK to commit?
