WholeProgramDevirt: Add import/export support for targets without absolute symbol constants. Not all targets support the use of absolute symbols to export constants. In particular, ARM has a wide variety of constant encodings that cannot currently be relocated by linkers. So instead of exporting the constants using symbols, export them directly in the summary. The values of the constants are left as zeroes on targets that support symbolic exports. This may result in more cache misses when targeting those architectures as a result of arbitrary changes in constant values, but this seems somewhat unavoidable for now.
