This avoids extra if statements in the common case of just comparing
two expressions that don't involve assignments or function calls,
along with simplifying the handling of constant expressions. Reduces
i965 instructions generated in unigine tropics and sanctuary,
yofrankie, warsow, gstreamer shaders, and the weston compositor.
shader-db results:
Total instructions: 213052 -> 212752
38/1246 programs affected (3.0%)
14309 -> 14009 instructions in affected programs (2.1% reduction)
Before, we were only counting top-level instructions. But if we have
an assignment of a giant expression tree (such as the ones eventually
generated by glsl-fs-unroll), we were counting the same as an
assignment of a variable deref.
glsl-fs-unroll-explosion now fails in a reasonable amount of time on
i965 because the unrolling didn't go ridiculously far.

Both callers of rewrite_tail immediately compute the new total string
length by adding the (known) length of the existing string plus the
length of the newly appended text. Unfortunately, callers generally
won't know the length of the new text, as it's printf-formatted.
Since ralloc already computes this length, it makes sense to add it in
and save the caller the effort. This simplifies both existing callers,
but more importantly, will allow for cheap-appending in the next commit.
v2: The link_uniforms code needs both the old and new length.
Apply the obvious fix (which sadly makes it less of a cleanup).

Avoid unrollong loops that are either nested loops or
where the loop body times the unroll count is huge.
The change is far from being perfect but it extends the
loop unrolling decision heuristic by some additional
safeguard. In particular this cuts down compilation of
a shader precomputing atmospheric scattering integral
tables containing two nesting levels in a loop from
something way beyond some minutes (I never waited for
it to finish) to some fractions of a second.

In commit 6ecee54a9a a call to
talloc_reference was replaced with a call to talloc_steal. This was in
preparation for moving to ralloc which doesn't support reference
counting.
The justification for talloc_steal within token_list_append in that
commit is that the tokens are being copied already. But the copies are
shallow, so this does not work.
Fortunately, the lifetime of these tokens is easy to understand. A
token list for "replacements" is created and stored in a hash table
when a function-like macro is defined. This list will live until the
macro is #undefed (if ever).
Meanwhile, a shallow copy of the list is created when the macro is
used and the list expanded. This copy is short-lived, so is unsuitable
as a new parent.
So we can just let the original, longer-lived owner continue to own
the underlying objects and things will work.

The trick here is that flex always chooses the rule that matches the most
text. So with a input text of "two:" which we want to be lexed as an
IDENTIFIER token "two" followed by an OTHER token ":" the previous OTHER
rule would match longer as a single token of "two:" which we don't want.
We prevent this by forcing the OTHER pattern to never match any
characters that appear in other constructs, (no letters, numbers, #,
_, whitespace, nor any punctuation that appear in CPP operators).

Exporting a publicly visible class with a generic name like
"variable_entry" via ir_variable_refcount.h is kind of mean.
Many IR transformers would like to define their own "variable_entry"
class. If they accidentally include this header, the compiler/linker
may get confused and try to instantiate the wrong variable_entry class,
leading to bizarre runtime crashes.
The hope is that renaming this one will allow .cpp files to safely
declare and use their own file-scope "variable_entry" classes.
This avoids crashes caused by converting src/glsl to automake.

This worked on C99-compliant compilers, since the s-expression reader
uses strtod() to read numbers, and C99 requires strtod() to understand
"+INF". However, it didn't work on non-C99-compliant compilers such
as MSVC.
This patch modifies the s-expression reader to explicitly check for
"+INF" rather than relying on strtod() to support it.
