rillig | libc: suppress lint warning for namespacing mismatch for _mcount
This is the last remaining instance of lint warning 215, which is about
implicitly defined functions. Since C99, these implicit declarations
have not been allowed anymore.

mrg | fixes for GCC 6:
- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair

Fix profiling on CPUs that do not support unaligned memory access;
Allocate objects (referenced from struct gmonparam) with proper
alignments.
For monstartup(), objects are allocated on heap. Break is not
guaranteed to be aligned at all, unlike stack pointer.
For _m_gmon_alloc(), objects are allocated on anonymous memory.
p->tos is not aligned properly in general.
This fixes quasi-random crashes for *_profile tests, at least on
SH-4 and PowerPC 403 [1]. Also, no regression is observed for
others as far as I can see.
This change does not cause any ABI breakage, as long as application
uses proper pointers; use p->tos instead of evil pointer arithmetic
like (struct tostruct *)((char *)p->froms + p->fromssize) [2].
[1] Timeout should be increased for some tests. "pic" variants
still fail as expected. Dynamically-linked binaries also crash in
rtld for SH-4, but this seems different problem...
[2] This example did not work even before, since the order of
froms[] and tos[] is reversed depending on which of monstartup() or
_m_gmon_alloc() is used for allocation.

use p->hashfraction when doing non-time-critical calculations, rather than
using HASHFRACTION directly. in time-critical calculations, if HASHFRACTION
is a power of two, check that p->hashfraction == HASHFRACTION and if so do
the calculation with the compiled-in value so that the compiler can optimize
out (potentially) expensive divisions. if p->hashfraction != HASHFRACTION,
actually do the division. This has the result that on machines with slow
division, the division can be optimized out of the common case, but that
if HASHFRACTION changes from the compiled-in value (for whatever reason),
profiling will still work. Changes suggested by Chris Torek.
