Reduce the number of ifdefs in machine independent code
Hopefully we don't have too many GNUC users who don't have
fetch and add.

Apply UNW_ALIGN more in src/mi/mempool.c
Apply UNW_ALIGN in a few places in src/mi/mempool.c that I missed in
commit c2f757418 ("Rename and share `ALIGN' macro from
_UCD_internal.h").

Simplify `sos_alloc()' implementation
Instead of maintaining a pointer to the `sos_memory' array, maintain an
index that tells the next free position. When atomic operations are
available, the allocation boils down to a single fetch-and-add
operation.

Align `sos_memory' to MAX_ALIGN
We give aligned pointers from the `sos_memory' array, so any non-aligned
bytes are only wasted.

Workaround non-power-of-two i386 sizeof(long double) in src/mi/mempool.c
To ensure that we return properly aligned pointers from sos_alloc(),
MAX_ALIGN must be a power-of-two. On i386 the power-of-two assumption
fails as sizeof(long double) = 12. Fix this by rounding up to 16.

Use GCC __BIGGEST_ALIGNMENT__ for sos-pool MAX_ALIGN
Use the __BIGGEST_ALIGNMENT__ macro provided by GCC for sos_alloc()
allocation alignment. The macro gives ``the largest alignment ever used
for any data type on the target machine you are compiling for.''
__BIGGEST_ALIGNMENT__ also has some other nice properties, e.g. it is
power-of-two on all architectures (note that on i386, sizeof(long
double) = 12), and on some architectures (e.g. SuperH) the alignment
requirement can be lower than sizeof(long double).

Rename and share `ALIGN' macro from _UCD_internal.h
Rename the `ALIGN' macro to `UNW_ALIGN', and move it from
`_UCD_internal.h' to `libunwind_i.h' so that we can share it with the
mempool code. `ALIGN' was clashing with system headers on FreeBSD:
In file included from src/coredump/_UCD_access_reg_freebsd.c:26:
