Implement FFI_EXEC_TRAMPOLINE_TABLE allocator for iOS/ARM.
...
This provides working closure support on iOS/ARM devices where
PROT_WRITE|PROT_EXEC is not permitted. The code passes basic
smoke tests, but requires further review.

Add a hard-coded FFI_EXEC_TRAMPOLINE_TABLE arm implementation.
...
This implements support for re-mapping a shared table of executable
trampolines directly in front of a writable configuration page, working
around PROT_WRITE restrictions for sandboxed applications on Apple's
iOS.
This implementation is for testing purposes; a proper allocator is still
necessary, and ARM-specific code needs to be moved out of
src/closures.c.

Add a shell script that generates the ARM trampoline page.
...
This generates a page of 340 trampolines, aligned within one page. The
trampolines use pc-relative addressing to reference config data
(context, jump address) from a page placed directly prior to the
trampoline page. This can be used on systems -- such as iOS -- that do not
support writable, executable memory by remapping the executable page
containing the trampolines directly above a newly allocated writable
config page.

not permitted for sandboxed binaries.

Work-around libffi's FP ABI detection.
...
On iOS, we must use the AAPCS floating point return value calling
conventions. libffi's ARM implementation will only use these conventions
if __SOFTFP__ is defined, which is not the case when GCC's
-mfloat-abi defaults to 'softfp' instead of 'soft'. To work around this
we manually define __SOFTFP__ for Apple platforms in the ARM-specific
sysv.S.
