Subject: [PATCH] tcg: Move definition of type TCGv

The target-dependant type TCGv must be defined in "tcg/tcg.h" before
including the tracing helper wrappers in "tcg/tcg-op.h".

It also makes more sense to define it here, where other TCG types are
defined too.

Backports commit 5d4e1a1081d3f1ec2908ff0eaebe312389971ab4 from qemu
