fbc7c0b8f2 Make function bodies rely on the parameter variable declarations. 
Previously, generating inlined function bodies was going to be
difficult, as there was no mapping between the body's declaration of
variables where parameter values were supposed to live and the
parameter variables that a caller would use in paramater setup.
Presumably this also have been a problem for actual codegen.

894ea972a4 Put function bodies under function signatures, instead of flat in the parent. 
This will let us know the length of function bodies for the purpose of
inlining (among other uses).

c178c74c27 Add tracking for extension based warnings 
Using '#extension foo: warn' instructs the compiler to generate a
warning when some feature of the extension 'foo' is used.  This patch
adds some infrastructure needed to support that for variables.

Similar changes will be needed for types and built-in functions.

8c46ed2490 Generate correct IR for do-while loops 
Previously the same code was generated for a while loop and a do-while
loop.  This pulls the code that generates the conditional break into a
separate method.  This method is called either at the beginning or the
end depending on the loop type.

fad607a9be Add ir_loop to represent loops 
This touches a lot of files because everything derived from ir_visitor
has to be updated.  This is the primary disadvantage of the visitor pattern.

63f394203a Set lower bound on size implied by whole-array assignment 
When an unsized array is accessed with a constant extension index this
sets a lower bound on the allowable sizes.  When the unsized array
gets a size set due to a whole-array assignment, this size must be at
least as large as the implied lower bound.

This causes the following tests to pass:
