fbdf40f86a Fix cases where we missed inlining some more obvious candidates because the 
caller was in an SCC.

fee8ce6131 Fairly substantial changes to update the alias analysis we are querying as 
we make the transformation.  This allows us to use interprocedural alias
analyses successfully.

that do not have builtin support for garbage collection.

dd4c06d2bf Changes to work with the changes to the AliasAnalysis interface. The -no-aa 
class is now in the BasicAliasAnalysis.cpp file

7ccc4c2ed9 Move the -no-aa AA implementation into this file since both of these 
alias analysis implementations are special: they do not autoforward to a
chained implementation of alias analysis

assert.

bdc2cf6dec Several *major* changes to the AA interfaces: 
1. Provide interfaces so that clients can update alias analyses to reflect
   the changes made by the transformations.
2. Change how alias analysis implementations work overall.  In particular,
   now clients will automatically forward to chained AA implementations: they
   don't have to remember to do it themselves.

6c96206c1e Update the coding standards, removign the bit about avoiding exceptions and 
rtti (they shouldn't be used in the main compiler, but that's because
optimizations aren't allowed to fail!)

Remove the big section about iterators, because people who do not know what
they are doing shouldn't be writing them.  :)

b6b757041b Various changes to make the docs look nicer. Add a new doc_author class. 
The one thing that someone (misha?) should look at is fixing doc_code so that it sizes to fit the code instead of going to the right margin all of the way.  Fixing it at a particular number of pixels was just wrong. :)

b8938f3fec Remove virtual destructor from InstVisitor. This class should never be 
used through a base pointer/reference so inproper destruction should
never be an issue. Removing this last virtual function also saves 4
bytes off each InstVisitor instance.

ff53779015 Added a "Miscellaneous Improvements" section to cover things like the 
Bytecode File Format documentation, getting all documents in HTML 4.01
(Strict) compliance, and any other minor improvement that shoud be noted.

of the global type pool and symbol table. More still to come.

35a7240e8a Remember the set of leaders. Also compute on demand and cache the equiv 
class for each leader.   Finally, rename Elem2ECLeaderMap to Elem2LeaderMap
(most of the changed lines are only due to the latter).
