mesa: better function inlining in the presence of 'return' statements
Before, the presence of a 'return' statement always prevented inlining
a function. This was because we didn't want to accidentally return from
the _calling_ function. We still need the semantic of 'return' when
inlining
but we can't always use unconditional branches/jumps (GPUs don't always
support arbitrary branching).
Now, we allow inlining functions w/ return if the return is the last
statement in the function. This fixes the common case of a function
that returns a value, such as:
vec4 square(const in vec4 x)
{
return x * x;
}
which effectively compiles into:
vec4 square(const in vec4 x)
{
__retVal = x * x;
return;
}
The 'return' can be no-op'd now and we can inline the function.
