compiler/glsl: fix precision problem of tanh
Clamp input scalar value to range [-10, +10] to avoid precision problems
when the absolute value of input is too large.
Fixes dEQP-GLES3.functional.shaders.builtin_functions.precision.tanh.* test
failures.
v2: added more explanation in the comment.
v3: fixed a typo in the comment.
