More expr tests and fixes
*: Add tests/expr-new.test from Tcl
*: Directly convert from int to double if possible
*: Always treat '-' in front of a number as unary minus
so that '-0x1234' works.
*: Fix expr when the variable does not exist
*: Add optional support for math functions
*: Also double/0 == Inf or -Inf
