Adds git hash to compiler's version switch. Refs #1119.
Fixed parsing of float literals.

Float literals were not parsed properly when their fractional part
exceeded 53 significant bits. This affected in particular math.PI
and math.E. Rather than reinventing the wheel, this patch reuses
C's strtod() implementation, which already does the heavy lifting
with respect to correctness, though some caution is necessary to
keep float parsing locale-independent.
Add support for structs/unions defined in structs/unions
Added test for anonymous structs and unions
Removed time and added a hash based on filename, line and column for creating a unique struct id
More human readable `$`(float)

The output matches that of Python (eg 1e100, not 1.0e100), but also
reflects locale (assuming it was set using setlocale() before).
Tests for `$`(float)
