… default

- S-mode trap handler is a copy of the M-trap handler with minor modifications

- fix error in loading from/to mem in the load/store page fault handler
- fix temp registor back-up and restore arrangement to not overwrite values required for test execution

- add try and except for checking the pte_dict from the plugin for superpage and misaligned page flags
- update the setup_page function call in the test.

…g mode

- update the trap handler to handle misaligned giga and mega page faults
- update the setup_pages function in utils to generate misaligned superpages

- make a0 and a1 registers zero when terapage/petapages are generated by plugin so that misaligned tera/petapage are not attempted to handle by the traphandler

- add a new ``possible_superpage_privilege`` dictionary containing the possible superpage configurations based on privilege mode
- update the existing ``possible_superpage_variants`` with tera and petapage to enable their generation
- remove redundant comment in test_generator

merge superpage to dev

fix the misaligned page handling in the load/store and instruction page fault handlers by directly updating the faulting PTE with a valid aligned address.

- fix misaligned superpage test generation

As mentioned in #21, this commit attempts to split the arch test file into
privileged and upnprivileged files which contain the macros as mentioned in the issue.

…t files

- in utils, the macro parser method is updated to parse macros in both the header files
- the test generator parses the compile_macros list returned by the plugin and Identifies if the privileged header needs to be included. If the privileged header is required, a new macro ``privileged_test_enable`` is added to the compile_macros list returned from the plugin

split arch_test into arch_test_priv and arch_test_unpriv

- update outdated supervisor trap handler to match with the machine handler
- remove errors in trap handling
