Fixes the way we check if flattening happened during canonicalization. We now check whether the returned coercion is an identity coercion. We used to check whether we return any constraints from flattening but that's wrong in the presence of the flattening cache.

Use Unicode private-use characters for roundtripping This replaces the previous scheme (which used lone surrogates). The reason is that there is Haskell software in the wild (i.e. the text package) that chokes on Char values that do not represent Unicode characters. This new approach will not work correctly if the reserved private-use characters are actually encountered in the input, but we expect this to be rare.

Introducing: 1) Postponing the application of instances when there is a possibility of a given matching. With the addition of prioritizing equalities this fixes #5002 and #4981. 2) Implemented caching of flattening in constraint simplification. This improves efficiency (fixes #5030) 3) Simplified pushing of unsolved wanteds (now pushing only equalities) inside implications.

Big patch to improve Unicode support in GHC. Validated on OS X and Windows, this patch series fixes #5061, #1414, #3309, #3308, #3307, #4006 and #4855. The major changes are: 1) Make Foreign.C.String.*CString use the locale encoding This change follows the FFI specification in Haskell 98, which has never actually been implemented before. The functions exported from Foreign.C.String are partially-applied versions of those from GHC.Foreign, which allows the user to supply their own TextEncoding. We also introduce foreignEncoding as the name of the text encoding that follows the FFI appendix in that it transliterates encoding errors. 2) I also changed the code so that mkTextEncoding always tries the native-Haskell decoders in preference to those from iconv, even on non-Windows. The motivation here is simply that it is better for compatibility if we do this, and those are the ones you get for the utf* and latin1* predefined TextEncodings anyway. 3) Implement surrogate-byte error handling mode for TextEncoding This implements PEP383-like behaviour so that we are able to roundtrip byte strings through Strings without loss of information. The withFilePath function now uses this encoding to get to/from CStrings, so any code that uses that will get the right PEP383 behaviour automatically. 4) Implement three other coding failure modes: ignore, throw error, transliterate These mimic the behaviour of the GNU Iconv extensions.

Make the GHCi linker handle partially stripped object files (#5004) When you use 'strip --strip-unneeded' on a ELF format .o or .a file, if the object file has no global/exported symbols then 'strip' ends up removing the symbol table entirely. Previously the GHCi linker assumed there would always be exactly one symbol table and exactly one string table. In fact, in ELF object files there is no such limitation, instead each section points to the other sections it needs, in particular relocation sections have a link to the symbol table section they use and symbol table sections have a link to the corresponding string table. So instead of assuming there will always be a global symbol and string table, all we have to do is validate and follow these links. Then, when we encounter an empty object file that has no symbols then we handle it correctly, because since it's empty we never process any relocations and so never have to follow any links to non-existant symbol tables. Also, in the case where an object is fully stripped, we can now detect this more reliably and emit a more helpful error message, e.g: libHSghc-7.1.20110509.a(DsMeta.o): relocation section #2 has no symbol table This object file has probably been fully striped. Such files cannot be linked.
