5f705671e4 Here is the bulk of the sanitizing. 
Almost all occurrences of "bytecode" in the sources have been eliminated.

354f02e03d Generalize MVT::ValueType and associated functions to be able to represent 
extended vector types. Remove the special SDNode opcodes used for pre-legalize
vector operations, and the special MVT::Vector type used with them. Adjust
lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.

This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.

1509e17e6c temporarily revert reid's asmwriter patch, it is missing the asmparser piece 
that decodes the escape sequences, thus breaking all cases that use them.

7170d7ab1b Adjust how LLVM names are produced: 
1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments
   to the name can be done in one pass.
3. Implement generation of hex escapes so we don't get "wonky" characters
   in the output.

da3b0264f7 if functiontype is going to have a pointer to a paramattr object, it better 
be const.  The only way to get a pointer to these returns a const pointer.

8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
