Use llabs when getting the absolute value of a long long.

MFC 275415:

Allow the UAL APSR_nzcv format for the mrc and mrc2 instructions. The clang
integrated assembler only allows these forms so binutils will need to
support them.

MFC 275584:

Fix mrc and mrc2 with APSR_nzcv. Binutils encodes it internally as 0 where
we need it to be set to 15 for it to be equivalent to r15.

There is no need to use FUNC_END with aeabi_ldiv0 or aeabi_idiv0 as they
are aliases.

MFC 275380:

Use the floating-point instruction on ARMv7 as the clang 3.5 integrated
assembler doesn't allow these two instructions to use co-processor 11.

Pull in the NetBSD global offset table handling code. Clang 3.5 creates
relocations the linker complains about.

MFC 275564:

Use the unified syntax when generating assembly for clang. The clang 3.5
integrated assembler only accepts it.

MFC r268576: sh: Correctly handle positional parameters beyond INT_MAX on
64-bit systems.

Currently, there can be no more than INT_MAX positional parameters. Make
sure to treat all higher ones as unset to avoid incorrect results and
crashes.

On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and
sign-extends them.

On 32-bit systems, the call to atoi() returned INT_MAX for too high values
and there is not enough address space for so many positional parameters, so
there was no issue.
