3cec66512d Implement do/while loops. Replace IR_CJUMP with IR_CJUMP0 and IR_CJUMP1 so
we can either jump on zero, or non-zero predicate.

eb0c478b17 Rewrite a bunch of constructors. It's now important that the first
constructor for any given type be the one that takes the most parameters
as this is the constructor that'll be used when there's no perfect match
to the caller's arguments.
See the _slang_adapt_call() function for details.

3a3bb953b6 _slang_gen_function_call_name() now tries to adapt function calls (expand
vectors, insert casts) when a perfect match isn't found.

eabb7e66bd New _slang_adapt_call() function.
This is used to modify function calls (when possible) to make the arguments
map to the function parameters.  This includes "unrolling" vector types
and doing casts.

Example:
   vec2 v2 = vec2(1.2, 3.4)
   ivec3 iv = ivec3(false, v2);
Is converted into:
   ivec3 iv = ivec3(int(false), int(v2[0]), int(v2[1]))

f6507157e2 Reimplement the post-increment/decrement functions.
Instead of defining functions with an extra dummy parameter to distinguish
from the pre-incr/decr functions, just use new function names: __postIncr
and __postDecr.
