Rip out object splittingwip/kill-obj-splitter
The splitter is an evil Perl script that processes assembler code.
Its job can be done better by the linker's --gc-sections flag. GHC
passes this flag to the linker whenever -split-sections is passed on
the command line.
This is based on @DemiMarie's D2768.
Fixes Trac #11315
Fixes Trac #9832
Fixes Trac #8964
