This patch changes the ENTRY() macro in asm.h to create a new section for every assembler function, thus providing dcache_clean/invalidate_all and friends with the same --gc-sections goodness that our C functions have. This requires a few minor changes of moving around data (to make sure it ends up in the right section) and changing some libgcc functions (which apparently need to have two names?), but nothing serious. (You may note that some of our assembly functions have data, sometimes even writable, within the same .text section. This has been this way before and I'm not looking to change it for now, although it's not totally clean. Since we don't enforce read-only sections through paging, it doesn't really hurt.) BUG=None TEST=Nyan and Snow still boot. Confirm dcache_invalidate_all is not output into any binary anymore since no one actually uses it.
