remove interp section definition in comp.ld
- it does not make sense to specify this section manually and set a PHDR (.interp segment) for it, this may cause ld reporting errors because some Alloc type sections might be tried to put into the interp segment by the linker, but we don't have this segment in the final PHDR set.

- x86_64 ABI requires a 16-byte alignment for fetching data and when calling a function, because some instructions like movabs and sse require data to be 16-byte aligned. Otherwise, it will case a #GP

- .boottext section needs to be aligned to generate correct bootable image - the stack in loader.S needs to be set to .data section, the original .comm will generate a .bss section that could have random address after compiling

- fix the linker script so it can correctly compile a bootable image - add -nmagic flag to $(LD) in the Makefile so $(LD) does not add additional blank information to the bootable image

use a larger stack size in user level
- set stack size to be 4*4k, all_stack_size to be 66560*4 - this is because some applications like DPDK would require a larger stack size, or the stack could be corrupted

Step 1 & 2 in adding address space support to the composer: parsing a…
…nd validation of composition scripts, and added access to AS representation in the composer's state. The overall goal is to add full initargs support for address spaces, going all the way back to a specification for address spaces from the composition scripts. Steps: 1. DONE: parsing and validation of composition scripts. 2. DONE: add an AS representation to the pass structure of the composer for later pass access. 3. Order ASes by the parent relationship. 4. Assign virtual addresses based on ASes and the parent relation. 5. Synthesize the initargs based on the ASes and addresses. 6. Use the initargs and the AS specification in the booter.
