Add EABI support routines to raise SIGFPE on integer divide by 0.

Define htonl &co as alternative names to bswap only if little endian.
I'm not sure if idempotent versions need to be defined for big endian,
as the man page says in that case they are defined idempotent macros.

libc wants __bswapNN, kernel wants bswapNN. That was not accounted
for during the merge of kernel and libc versions. Fix to match
e.g. i386 code.

Merge libkern + libc common files. As requested by core.

arm bswap32: fix fatal typo in thumb code (PR 55854)

arm bswap32: Improve the comments showing the byte flow.

It's confusing to use 1-4 for bytes 1-4 and then 0 for literal zero,
so use a-d for bytes 1-4.

Add some comments to illustrate what is actually happening.

Include compiler-rt in libc, libm and libkern.

This is ARM only

Add support for __ARM_ARCH_EXT_IDIV__ which is set for those cores
with hardware divide instructions. Note that gcc 4.5.x doesn't support
this so this is just latent. gcc 4.7.x does.

When using EABI, call __aeabi_{i,l}div0 when diving by 0.

split udivsi3 and divsi3 to fix static linking. This could be done better.

Include compiler-rt in libc, libm and libkern.

Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.

Remove movw/movt due to linker problems.
Check for 0 divisor and __aeabi_idiv0 if needed (EABI && _LIBC only).

s/__libc/_libc/

Support using hwdiv instructions if those are available.
But only for EABI.

Use __ARM_EABI__ and new __UNWIND_TABLES__ to decide when to use .cfi ops

Don't include .cfi info if _KERNEL || _STANDALONE

Split out modsi3 and umodsi3 from the divsi3 file. This is so that
we don't get re-defined symbols in libc from libgcc in static linking.
Example: cc -pthread -static main-calls-pthread-create.c
