bf9a37ed83 Make sure we have all the dirty registers in user frames on the 
backing store before we discard them. It is possible that we
enter the kernel (due to an execve in this case) with a lot of
dirty user registers and that the RSE has only partially spilled
them (to make room for new frames). We cannot move the backing
store pointer down (to discard user registers) when not all of
the user registers are on the backing store.
So, we flush the register stack IFF this happens. Unconditionally
doing the flush is too costly, because the condition in which we
need to flush is very rare.

This change appears to fix the SIGSEGV that sometimes happen for
newly executed processes and so far also appears to fix the last
of the corruption. It is possible, although not likely, that this
change prevents some other bug from happening, even though it is
itself not a fix. Hence the uncertainty. We'll know in a couple
of months I guess :-)

9bba923f2e Fix ia32 compat on ia64. Recent ia64 MD changes caused the garbage on 
the stack to be changed in a way incompatible with elf32_map_insert()
where we used data_buf without initializing it for when the partial
mapping resulting in a misaligned image (typical when the page size
implied by the image is not the same as the page size in use by the
kernel). Since data_buf is passed by reference to vm_map_find(), the
compiler cannot warn about it.

While here, move all local variables to the top of the function.
