16183e6430 Implement constant sharing so that 4 float constants can share a single 
float[4] register slot.

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.

and __postDecr.
