btrace: fix gap indication
Trace gaps due to overflows or non-contiguous trace are ignored in the 'info
record' command. Fix that.
Also add a warning when decoding the trace and print the instruction number
preceding the trace gap in that warning message. It looks like this:
(gdb) info record
Active record target: record-btrace
Recording format: Intel Processor Trace.
Buffer size: 16kB.
warning: Decode error (-13) at instruction 101044 (offset = 0x29f0, pc = 0x7ffff728a642): no memory mapped at this address.
Recorded 101044 instructions in 2093 functions (1 gaps) for thread 1 (process 5360).
(gdb) record instruction-history 101044
101044 0x00007ffff728a640: pop %r13
[decode error (-13): no memory mapped at this address]
Remove the dead code that was supposed to print a gaps warning at the end of
trace decode. This isn't really needed since we now print a warning for each
gap.

* btrace.c (ftrace_add_pt): Fix gap indication. Add warning for non-
contiguous trace and overflow. Rephrase trace decode warning and print
instruction number. Remove dead gaps warning.
(btrace_compute_ftrace_bts): Rephrase warnings and print instruction
number.
