glsl: add several EmitNo* options, and MaxUnrollIterations
...
This increases the chance that GLSL programs will actually work.
Note that continues and returns are not yet lowered, so linking
will just fail if not supported.

Create a dummy context in the standalone compiler and pass it to
_mesa_glsl_parse_state.

glsl: Set default language version in mesa_glsl_parse_state constructor.
...
This should make it easier to change the default version based on the
API (say, version 1.00 for OpenGL ES).
Also, synchronize the symbol table's version with the parse state's
version just before doing AST-to-HIR. This way, it will be set when
it matters, but the main initialization code doesn't have to care about
the symbol table.

glsl2: Free the shader compiler at dri screen destruction.
...
Hooray, we can valgrind again without adding suppressions. This also
adds an interface for use by an implementation of
glReleaseShaderCompiler().

glsl2: Add a pass to strip out noop swizzles.
...
With the glsl2-965 branch, the optimization of glsl-algebraic-rcp-rcp
regressed due to noop swizzles hiding information from ir_algebraic.
This cleans up those noop swizzles for us.

glsl2: Move the common optimization passes to a helper function.
...
These are passes that we expect all codegen to be happy with. The
other lowering passes for Mesa IR are moved to the Mesa IR generator.

ast: Initialize location data in constructor of all ast_node objects.
...
This prevents using uninitialized data in _msea_glsl_error in some
cases, (including at least 6 piglit tests). Thanks to valgrind for
pointing out the problem!
