AltiVec SIMD implementation of slow integer forward DCT;  Clean up fast integer forward DCT code so that it is easier to see how it derives from the SSE2 code and to make it play more nicely with the slow FDCT code.

Further cleanup of the AltiVec forward DCT code:
-- Use macros to represent the fast FDCT constants, to facilitate comparing the AltiVec implementation of the algorithm with the SSE2 implementation.
-- Rename slow FDCT constants for consistency.
-- Use vec_sra() in all cases in the slow FDCT code.  The SSE2 implementation uses psraw, which is an arithmetic shift, so we need to do likewise with AltiVec.  Using vec_sr() hasn't caused any problems yet, but it is conceivable that it might cause different behavior in certain corner cases.

Add iOS architectures to the shared libraries generated by the Mac/iOS packaging system.  I have no idea how useful this is for "standard" iOS application development, but it is useful in a jailbreak environment, and iOS 8 supposedly allows shared libs in "official" apps as well.

Remove reference to install.txt, which we do not include from the IJG distribution

Modify the ARM64 assembly file so that it uses only syntax that the clang assembler in XCode 5.x can understand.  These changes should all be cosmetic in nature-- they do not change the meaning or readability of the code nor the ability to build it for Linux.  Actually, the code is now more in compliance with the ARM64 programming manual.  In addition to these changes, there were a couple of instructions that clang simply doesn't support, so gas-preprocessor.pl was modified so that it now converts those into equivalent instructions that clang can handle.

In the output of the configure script, indicate whether gas-preprocessor.pl is being used along with the assembler.
