Fix the x86 build with NASM 0.98. Since NASM 0.98 is the default version on OS X, we want to at least allow people to build 32-bit code with it, even though it can't properly build 64-bit code.

Fixed regression caused by a bug in the 32-bit strict memory access code in jdmrgss2.asm (contributed by Chromium to stop valgrind from whining whenever the output buffer size was not evenly divisible by 16 bytes.) On Linux/x86, this regression caused incorrect pixels on the right-hand side of images whose rows were not 16-byte aligned, whenever fancy upsampling was used. This patch also enables the strict memory access code on all platforms, not just Linux (it does no harm on other platforms) and removes a couple of pcmpeqb instructions that were rendered unnecessary by r836.

Eliminate the use of the MASKMOVDQU instruction, to speed up decompression performance by 10x on AMD Bobcat embedded processors (and ~5% on AMD desktop processors.)

Fixed non-fatal out-of-bounds read in SSE2 SIMD code reported by valgrind when decompressing a JPEG image to a bitmap buffer whose size was not a multiple of 16 bytes.

Make x86_64 SIMD code PIC friendly
Use RIP relative addressing as that works in both PIC and non-PIC mode.
