    arm: Thumb ALL the things!
    
    This patch switches every last part of Coreboot on ARM over to Thumb
    mode: libpayload, the internal libgcc, and assorted assembly files. In
    combination with the respective depthcharge patch, this will switch to
    Thumb mode right after the entry point of the bootblock and not switch
    back to ARM until the final assembly stub that jumps to the kernel.
    
    The required changes to make this work include some new headers and
    Makefile flags to handle assembly files (using the unified syntax and
    the same helper macros as Linux), modifying our custom-written libgcc
    code for 64-bit division to support Thumb (removing some stale old files
    that were never really used for clarity), and flipping the general
    CFLAGS to Thumb (some more cleanup there as well while I'm at it).
    
    BUG=None
    TEST=Snow and Nyan still boot.
