d2861d682a mesa/glsl: delete previously linked shaders earlier when linking
This moves the delete linked shaders call to
_mesa_clear_shader_program_data() which makes sure we delete them
before returning due to any validation problems.

It also reduces some code duplication.

From the OpenGL 4.5 Core spec:

   "If LinkProgram failed, any information about a previous link of
   that program object is lost. Thus, a failed link does not restore
   the old state of program.

   ...

   If one of these commands is called with a program for which
   LinkProgram failed, no error is generated unless otherwise noted.
   Implementations may return information on variables and interface
   blocks that would have been active had the program been linked
   successfully. In cases where the link failed because the program
   required too many resources, these commands may help applications
   determine why limits were exceeded."

Therefore it's expected that we shouldn't be able to query the
program that failed to link and retrieve information about a
previously successful link.

Before this change the linker was doing validation before freeing
the previously linked shaders and therefore could exit on failure
before they were freed.

This change also fixes an issue in compat profile where a program
with no shaders attached is expect to fall back to fixed function
but was instead trying to relink IR from a previous link.

1fb8c6df88 glsl/mesa: split gl_shader in two
There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.

The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.

We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

31dee99e05 mesa/glsl: stop using GL shader type internally
Instead use the internal gl_shader_stage enum everywhere. This
makes things more consistent and gets rid of unnecessary
conversions.

Ideally it would be nice to remove the Type field from gl_shader
altogether but currently it is used to differentiate between
gl_shader and gl_shader_program in the ShaderObjects hash table.

Add an option in order to ask to just print the InfoLog, without any
