897dbf6c67 Use an identical source file for the libc and the libkern version of 
divsi3.S, conditionally compiling the divide by zero case. This way,
after a change to the one, we can just copy it over to update the other
without creating ... problems. By Chris G.  Demetriou.

bc086d24af In the division core: if the highest bit of the dividend is set, 
we have to be careful when shifting the divisor. Test this.

This fixes PR 7760 by Richard Earnshaw.

0ae41d0984 Use the C version of ldexp(). The assembler version was broken in several 
ways (ldexp(0.0, 5000) returned +Inf, didn't do normalization/denormalization,

30dca7f7db Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d 
in their respective header files).  Add PSEUDO stubs for the old versions
of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

0ffda58ae9 A new implementation of _setjmp/_longjmp that uses the T_FLUSHWIN trap. 
This means the stack frame and program counter can restored directly
from the jmp_buf, eliminating the need to backtrack through frames
which does not work in all cases.
