Alex Crichton 021c2f3712 rollup merge of #20310: fhahn/issue-15877-model-lexer-range
This patch for #15877 uses Antlr's input lookahead (`_input.LA(1) != '.'`) to solve the conflict between the LIT_FLOAT and the range syntax.

Note that in order to execute the grammar tests, #20245 should land first.
