accel/tcg: Zero-pad PC in TCG CPU exec trace lines
In commit f0a08b0913befbd we changed the type of the PC from
target_ulong to vaddr. In doing so we inadvertently dropped the
zero-padding on the PC in trace lines (the second item inside the []
in these lines). They used to look like this on AArch64, for
instance:
Trace 0: 0x7f2260000100 [00000000/0000000040000000/00000061/ff200000]
and now they look like this:
Trace 0: 0x7f4f50000100 [00000000/40000000/00000061/ff200000]
and if the PC happens to be somewhere low like 0x5000
then the field is shown as /5000/.
This is because TARGET_FMT_lx is a "%08x" or "%016x" specifier,
depending on TARGET_LONG_SIZE, whereas VADDR_PRIx is just PRIx64
with no width specifier.
Restore the zero-padding by adding an 016 width specifier to
this tracing and a couple of others that were similarly recently
changed to use VADDR_PRIx without a width specifier.
We can't unfortunately restore the "32-bit guests are padded to
8 hex digits and 64-bit guests to 16 hex digits" behaviour so
easily.
