Fix undefined symbol errors on windows/arm
...
Fix undefined symbol linker errors when building rust for windows/arm
by excluding unneeded symbols. The errors are:
= note: lib.def : error LNK2001: unresolved external symbol __aeabi_memclr4
lib.def : error LNK2001: unresolved external symbol __aeabi_memclr8
lib.def : error LNK2001: unresolved external symbol __aeabi_memmove4
lib.def : error LNK2001: unresolved external symbol __aeabi_memmove8

Add "volatile" and "memory" clobber to asm! that doesn't fall through.
...
Use the "volatile" option and the "memory" clobber on inline asm that does
things like return directly, to reduce the chances of compilers rearranging
the code.

Handle aeabi aliasing
...
Objects in compiler-rt may have two symbols, so this makes sure that we don't
bring in those objects by accident by defining the aliases ourselves.

use AAPCS calling convention on all aeabi intrinsics
...
also, on ARM, inline(always) the actual implementation of the intrinsics so we
end with code like this:
```
00000000 <__aeabi_dadd>:
(implementation here)
```
instead of "trampolines" like this:
```
00000000 <__aeabi_dadd>:
(shuffle registers)
(call __adddf3)
00000000 <__adddf3>:
(implementation here)
```
