With the arrival of VK_KHR_shader_float_controls algebraic
optimizations for float types of the form (('fop', a, b), a) become
inexact depending on the execution mode.
For example, if we have activated SHADER_DENORM_FLUSH_TO_ZERO, in case
of a denorm value for the "a" parameter, we cannot return it still as
a denorm, it needs to be flushed to zero. Therefore, we mark now all
those operations as inexact.

Table 23.54 of the OpenGL 4.5 spec lists the minimum values for
GL_POINT_SIZE_RANGE as [1, 1]. So zero is not allowed (even though
arguably this could be useful for MSAA rendering, where a sub-1px
point might cover only some samples...)
This fixes the WebGL 2.0 conformance suite's state.gl-get-calls test
on Chromium on Linux, which uses desktop OpenGL. The test checks that
the minimum value of GL_ALIASED_POINT_SIZE_RANGE is 1. Unfortunately,
that query doesn't exist in desktop GL, so it checks POINT_SIZE_RANGE,
which is the anti-aliased value. There's not really anything better
for Chromium to do here, unfortunately. When running Chromium with
--api=es3, it maps it to the correct query and the test already works.
