TCG types will be transformed into the appropriate host types later on
in the tool. For example adding the following trace point:
tcg goto_ptr(TCGv_ptr ptr) "", "ptr=%p"
would trigger:
ValueError: Error at /home/alex/lsrc/qemu.git/./trace-events:149: Argument
type 'TCGv_ptr' is not allowed. Only standard C types and fixed size integer
types should be used. struct, union, and other complex pointer types should be
declared as 'void *'
Rather than expand ALLOWED_TYPES just directly handle TCGv types in
validate_type.
Fixes: 73ff061032 ("trace: only permit standard C types and fixed size integer
types")
