Use hand-written constants table on ARMv5+ for JPEG IDCT, and load four 16-bit constants at a time with ldrd. Not useful for ARMv4, since one load per constant would still be needed, and limited range of ldrsh would force multiple copies of table. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21535 a1c6a512-1295-4272-9138-f99709370657
