  Move __objc_stubs symbols closer to symbols that jump to them when linking WebCore

Reviewed by Elliott Williams.

Without this change and with some other unrelated changes from PR 9342 that slightly
increase WebCore's binary size, I get some linker errors like this:

ld: b(l) ARM64 branch out of range (134310948 max is +/-128MB)

That is because we are linking jumps to symbols in the __objc_stubs section which are
very far away from other symbols jumping to them from the __text section.  To fix this,
simply rename __objc_stubs to __text to merge them together and decrease the maximum
jumps to nowhere near 128MB.
