Currently, --ignore-fn is only matched with the top IP entries that
have a fnname. With this change, we first search for the first IP that
has a fnname.
This e.g. allows to ignore the allocation for a stacktrace such as:
0x1 0x2 0x3 fn_to_ignore otherfn
This is then used in massif c++ tests new-cpp and overloaded-new to ignore
the c++ libstdc++ allocation similar to:
==10754== 72,704 bytes in 1 blocks are still reachable in loss record 10 of 10
==10754== at 0x4C2BBCD: malloc (vg_replace_malloc.c:299)
==10754== by 0x4EC39BF: ??? (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.22)
==10754== by 0x400F8A9: call_init.part.0 (dl-init.c:72)
==10754== by 0x400F9BA: call_init (dl-init.c:30)
==10754== by 0x400F9BA: _dl_init (dl-init.c:120)
==10754== by 0x4000C59: ??? (in /lib/x86_64-linux-gnu/ld-2.24.so)
for libstdc++ from gcc5.
Even with fix for bug 345307 we still see allocations for
the emergency pool in libstdc++ which skew the expected results.

- Added a new time unit, instructions executed, and made it the default -- it's
much more reproducible and consistent than milliseconds. Requires IRSB
instrumentation and so slows down some programs (malloc-light ones such as
bzip2) by about 20%, others by less.
- ms_print now doesn't overwrite the x-axis in the graphs.
- Added a test for --detailed-freq and --max-snapshots

expands to the PID. Updated the tests. Still todo: handle %q for
environment variables, and do the same for the core and
Cachegrind/Callgrind.

sizes up to a multiple of 8 (or whatever --alignment is). This is combined
with the "admin" bytes, resulting in the "extra" bytes. Added
VG_(malloc_usable_size) to the tool interface to support this.

- ms_main.c: completely overhauled.
- massif/tests/*: lots of them now.
- massif/perf/: added.
- massif/hp2ps: removed. No longer used.
- vg_regtest: renamed the previously unused "posttest" notion to "post".
Using it for checking ms_print's output.
Although the code has changed dramatically, as has the form of the tool's
output, the information presented in the output is basically the same,
although it's now (hopefully) much more useful. So the tool name is
unchanged.
