glsl: Avoid massive ralloc_strndup overhead in S-Expression parsing.
When parsing S-Expressions, we need to store nul-terminated strings for
Symbol nodes. Prior to this patch, we called ralloc_strndup each time
we constructed a new s_symbol. It turns out that this is obscenely
expensive.
Instead, copy the whole buffer before parsing and overwrite it to
contain \0 bytes at the appropriate locations. Since atoms are
separated by whitespace, (), or ;, we can safely overwrite the character
after a Symbol. While much of the buffer may be unused, copying the
whole buffer is simple and guaranteed to provide enough space.
Prior to this, running piglit-run.py -t glsl tests/quick.tests with GLSL
1.30 enabled took just over 10 minutes on my machine. Now it takes 5.
NOTE: This is a candidate for stable release branches (because it will
make running comparison tests so much less irritating.)

ir_reader: Remove s_list::length() method.
Most code now relies on the pattern matcher rather than this function,
and for the only remaining case, not using this saves an iteration.

ir_reader: Add a pattern matching system and use it everywhere.
Previously, the IR reader was riddled with code that:
1. Checked for the right number of list elements (via a linked list walk)
2. Retrieved references to each component (via ->next->next pointers)
3. Downcasted as necessary to make sure that each sub-component was the
right type (i.e. symbol, int, list).
4. Checking that the tag (i.e. "declare") was correct.
This was all very ad-hoc and a bit ugly. Error checking had to be done
at both steps 1, 3, and 4. Most code didn't even check the tag, relying
on the caller to do so. Not all callers did.
The new pattern matching module performs the whole process in a single
straightforward function call, resulting in shorter, more readable code.
Unfortunately, MSVC does not support C99-style anonymous arrays, so the
pattern must be declared outside of the match call.

glsl: new glsl_strtod() wrapper to fix decimal point interpretation
We always want to use '.' as the decimal point.
See http://bugs.freedesktop.org/show_bug.cgi?id=24531
NOTE: this is a candidate for the 7.10 branch.

glsl: Replace sscanf in s_expression reader with strspn and strcspn.
This seems to give roughly a 20% speedup.
