e95586f61e core: Fix IR generation of for loop containing break/continue
Fix cases where the body BB would have two terminators because of a
preceding continue/break statement already emitting a terminator.

48c6498d1f core: Fix restoration of loop target in try statement
old_loop_target is only assigned if ctx.loop_target is overwritten,
meaning that if ctx.loop_target is never overwritten, ctx.loop_target
will always be overwritten to None.

We fix this by only restoring from old_loop_target if we previously
assigned to old_loop_target.

31dcd2dde9 core: Use i8 for boolean variable allocation
In LLVM, i1 represents a 1-byte integer with a single valid bit; The
rest of the 7 upper bits are undefined. This causes problems when
using these variables in memory operations (e.g. memcpy/memmove as
needed by List slicing and assignment).

We fix this by treating all local boolean variables as i8 so that they
are well-defined for memory operations. Function ABIs will continue to
use i1, as memory operations cannot be directly performed on function
arguments or return types, instead they are always converted back into
local boolean variables (which are i8s anyways).

Fixes #315.

e0de82993f core: Preserve value of variable shadowed by for loop
Previously, the final value of the target expression would be one after
the last element of the loop, which does not match Python's behavior.

This commit fixes this problem while also preserving the last assigned
value of the loop beyond the loop, matching Python's behavior.

6de0884dc1 core: Use anonymous name for variables if unspecified
The current default prefix is only derived from the instruction type,
which is not helpful during the comprehension of the IR. Changing to
anonymous names (e.g. %1) helps understand that the variable is only
needed as part of a larger (possibly named) expression.

f1b0e05b3d core: Rename IR variables
Because it is unclear which variables are expressions and
subexpressions, all variables which are previously anonymous are named
using (1) the control flow statement if available, (2) the possible name
of the variable as inferred from the variable name in Rust, and (3) the
"addr" prefix to indicate that the values are pointers. These three
strings are joint together using '.', forming "for.i.addr" for instance.

ff23968544 core: Add name parameter to gen_{var_alloc,store_target}
This allows variables in the IR to be assigned a custom name as opposed
to names with a default prefix.

7ea5a5f84d nac3core: codegen refactoring
- No longer check if the statement will return. Instead, we check if
  the current basic block is terminated, which is simpler and handles
  exception/break/continue better.
- Use invoke statement when unwind is needed.
- Moved codegen for a block of statements into a separate function.

b267a656a8 nac3core: added exception type and fixed primitive representation
- Added `Exception` primitive type and some builtin exception types.
  Note that all exception types share the same layout, and should
  inherit from the base `Exception` type. There are some hacks in the
  toplevel module for handling exception types, we should revisit and
  fix them later.
- Added new primitive types to concrete type module, otherwise there
  would be some weird type errors.
- Changed the representation of strings to CSlice<u8>, instead of
  CString.
