We were returning the negative absolute value, instead of the absolute
value. Fixes glsl-vs-abs-neg.

(cherry picked from commit 9351ef7a44)
In general, we have to negate in immediate values we pass in because
the src1 negate field in the register description is in the bits3 slot
that the 32-bit value is loaded into, so it's ignored by the hardware.
However, the src0 negate field is in bits1, so after we'd negated the
immediate value loaded in, it would also get negated through the
register description. This broke this VP instruction in the position
calculation in civ4:
MAD TEMP[1], TEMP[1], CONST[256].zzzz, CONST[256].-y-y-y-y;

global are pulled into the linked shader.

Previously only global arrays with implicit sizes would be patched.

The rvalue of the returned value can be NULL if the shader says
'return foo();' and foo() is a function that returns void.
Existing GLSL specs do *NOT* say that this is an error. The type of
the return value is void. If the return type of the function is also
void, then this should compile without error. I expect that future
versions of the GLSL spec will fix this (wink, wink, nudge, nudge).

The removed semantic check also exists in ast_type_specifier::hir(), which

Change default value to ast_precision_none, which denotes the absence of
a precision of a qualifier.
Previously, the default value was ast_precision_high. This made it
impossible to detect if a precision qualifier was present or not.

This is similar to commit 0efea25c in 7.10. The change was made
directly in the 7.9 branch because the affected code does not exist in
Mesa 7.10 or later. It was removed with the change to the new
fragment shader back-end.
Fixes the GPU hang in piglit test glsl-fs-discard-03.

When GCC encounters a division by zero in a preprocessor directive, it
generates an error. Since the GLSL spec says that the GLSL
preprocessor behaves like the C preprocessor, we should generate that
same error.
It's worth noting that I cannot find any text in the C99 spec that
says this should be an error. The only text that I can find is line 5
on page 82 (section 6.5.5 Multiplicative Opertors), which says,
"The result of the / operator is the quotient from the division of
the first operand by the second; the result of the % operator is
the remainder. In both operations, if the value of the second
operand is zero, the behavior is undefined."

Previously the 'STDGL invariant(all)' pragma added in GLSL 1.20 was
simply ignored by the compiler. This adds support for setting all
variable invariant.
In GLSL 1.10 and GLSL ES 1.00 the pragma is ignored, per the specs,
but a warning is generated.
