Markus Metzger da8c46d296 btrace: indicate speculative execution 
Indicate speculatively executed instructions with a leading '?'.  We use the
space that is normally used for the PC prefix.  In the case where the
instruction at the current PC had been executed speculatively before, the PC
prefix will be partially overwritten resulting in "?> ".

As a side-effect, the /p modifier to omit the PC prefix in the "record
instruction-history" command now uses a 3-space PC prefix "   " in order to
have enough space for the speculative execution indication.
