FS#11335 by me: make ARM assembly functions thumb-friendly
...
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

Refacturate arm version of libmad's synthesis filter. Only two asm macros left, renamed asm-implementation for better clarity. No change in speed or precision.

* ARM asm DSP and codec/plugin functions: Use r12 scratch register properly
...
* Fix saving another unused reg in dsp code
* Use less regs in the generic ARM mpegplayer adding idct pure DC case
* Fix ARMv6 mpegplayer adding idct using an unsaved register in pure DC case

Revert r14050 (apart from the non-related whitespace changes) and fix the S3C2440 (Gigabeat F/X) problems introduced by my r14041 commit in a slightly different way: Introduce a mad_iram.h file and centralise all IRAM-related decisions in there (similar to how Tremor does it). Now checks for CPU type (S3C2440) instead of target (TOSHIBA_GIGABEAT_F) and there is also a .ibss variable in syth_full_arm.S which shouldn't go in IRAM on S3C2440 targets. Closes FS#7500

Fix mp3 playback on the gigabeat by not putting code in IRAM. Someone actually familar with the gigabeat port should check this.

FS #6705 - ARM optimisations for libmad by Tomasz Malesinski. Modified slightly by me to not put code in IRAM for PP502x (it's slower), and for the mpegplayer version of libmad for PP5002 (there isn't enough room). On my ipod Color, it increases a 320kbps MP3 test file from 169% realtime to 188% realtime. Reported speedup on the ipod 3G was from 118% to 155% realtime for a 192kbps MP3.
