Commit 85097db6 changed the timing when kvm_allowed is set until after
kvm is initialized.  During initialization, the ioeventfd initialization code
checks kvm_enabled() and after this change, ioeventfd is effectively disabled.

This causes a significant regression in performance.

Fix this by setting kvm_allowed before calling init.

When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct
from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to
manipulate a TCGv_ptr will always be detected at compile time, rather
than only if compiling on a host system with the other word size.

NB: the tcg_add_ptr and tcg_sub_ptr macros have been removed as they
were not used anywhere.

The prototypes for the ld/st functions on a 64 bit host declared
the address parameter as a TCGv_i64 rather than a TCGv_ptr. This
worked OK (since the two are aliases), but needs to be fixed to
allow extension of TCG type debugging to i64/i32/ptr mismatches.

The disas_a5() function provided a TCG tmp variable which was populated
by the respective opcode implementations, but freed at the end of the

That makes it really hard for code review, so let's move the freeing
