compiler: new "binary literal area" at the end of a word's machine code stores constant floats and SIMD vectors; this allows ##load-reference/##load-memory fusion to be performed on x86-64, with a RIP-relative address reaching the data; also simplifies VM since custom relocation types used by the previous 32-bit-only optimization are no longer needed

Change how non-volatile register preservation is done in alien callbacks, with the aim of fixing callbacks on PowerPC, and to eventually eliminate assembly code from VM
...
- Simplify calculation of offset in relocation table
- Open-code %alien-callback
- Remove magic_frame hack from context objects
- Move magical return instruction from optimizing compiler backend into callback entry stub

vm: big overhaul of non-optimizing compiler
...
- change some primitives into sub-primitives: fixnum+ fixnum- fixnum* inline-cache-miss inline-cache-miss-tail
- rename some relocation types for clarity
- some other minor re-organizations and cleanups

Big cleanup of literal table and relocation-related code
...
- new way to iterate over instruction_operands cleans up relocation code
- move some methods out of the VM class to clean up code
- if debugging is on, die earlier if attempting to allocate inside GC
- callback heap entries are now code_blocks
- replace block_granularity with data_alignment
