glsl: invalidate float suffixes for GLSL 1.10 and GLSL ES 1.00
Float suffixes are not allowed in GLSL 1.10 nor GLSL ES 1.00.
Fixes the following piglit tests:
tests/spec/glsl-1.10/compiler/literals/invalid-float-suffix-capital-f.vert
tests/spec/glsl-1.10/compiler/literals/invalid-float-suffix-f.vert`
v2: modify error message
v3: parse the float instead of returning an ERROR_TOK
v4: (by Ken) Change to is_version(120, 300) to avoid breaking ES3
shaders; update commit message accordingly.
