triggered by generated code (probably false positives). Fix some warnings in rts.c

Note that an alternative implementation choice is just to implement
them as SAIL functions manipulating a global variable.
Not sure which is better.

Also further tweaks to Sail library for C and include sail lib files for tracing

For example, the MIPS model can boot FreeBSD as
./mips_c --binary=0x100000,/path/to/kernel --image=/path/to/simboot.sailbin
Or with short options as
./mips_c -b 0x100000,/path/to/kernel -i /path/to/simboot.sailbin
The current options are:
-e, --elf, which loads an elf file directly
-n, --entry, which sets the entry point
-i, --image, which loads an image file compiled by "sail -elf" using Linksem
-b, --binary, which loads a plain binary image into memory at a specific address
-l, --cyclelimit, which means the (new) cycle_count() builtin exits the model after a certain number of calls
Also there are the default -? --help and --usage options.

Previously the ANF->IR translation cared too much about how things
were allocated in C, so it had to constantly check whether things
needed to be allocated on the stack or heap, and generate different
cequences of IR instructions depending on either. This change removes
the ialloc IR instruction, and changes iinit and idecl so that the
code generator now generates different C for the same IR instructions
based on the variable types involved.
The next change in this vein would be to merge icopy and iconvert at
the IR level so that conversions between uint64_t and large-bitvectors
are inserted by the code generator. This would be good because it
would make the ANF->IR translation more robust to changes in the types
of variables caused by flow-typing, and optimization passes could
convert large bitvectors to uint64_t as local changes.

Fix a bug involving indentifers on the left hand side of assignment
statements not being shadowed correctly within foreach loops.
Make the different between different types of integer division
explicit in at least the C compilation for now. fdiv_int is division
rounding towards -infinity (floor). while tdiv_int is truncating
towards zero. Same for fmod_int and tmod_int.
