0c49b30a90 core: Restore debug info before function call is invoked

Previously, the IR which sets up the call to the target function will
have its debug location pointing at the last argument of the function
call instead of the function call itself.

60a503a791 core: Allocate more stack variables at the beginning of function

All allocas for temporary objects are now placed in the beginning of the
function. Allocas for on-temporary objects are not modified because
these variables may appear in a loop and thus must be uniquely
allocated by different allocas.

a2fce49b26 core: Allocate exceptions at the beginning of function

Only one instance of exception is necessary, as exceptions will always
be initialized before being thrown.
