e90afea0ba Try r84890 again (adding ValueMap<>), now that I've tested the compile on 
gcc-4.4.

ad8692124f Add a ValueMap<ValueOrSubclass*, T> type. ValueMap<Value*, T> is safe to use 
even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.

It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.

98f201632e split raw_os_ostream out to its own header and implementation file. This 
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

6812c0db35 Add SmallVector::{capacity,set_size}. 
- These allow clients to make use of the extra elements in the vector which
   have already been allocated, without requiring them to be value initialized.

930c879b9e Modify APFloat to take a StringRef instead of a c string. 
This also adds unit tests to APFloat that mainly tests the
string handling of APFloat, but not much else of it's api.

d13fcdaae5 Twines: Support numeric conversion directly (uitostr, etc). 
- Provides static constructors for doing number to string conversions without
   using temporaries.

 - There are several ways to do this, I think given the Twine constraints this
   is the simplest one.

 - One FIXME for fast number -> hex conversion.

 - Added another comment on one last major bit of perf work Twines need, which
   is to make raw_svector_ostream more efficient.

5a9d56ab90 Update Triple to use StringRef/Twine based APIs. 
- This is now shorter, simpler, safer, and more efficient, what a deal.

da42799098 Add a missing ilist_node.h #include to SparseBitVector, and add a very short 
test for it. The test is by no means complete, but it tests the problem I was
fixing.

b5adc13728 Convert StringMap to using StringRef for its APIs. 
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

789c11dcc0 Reversed order of args in EXPECT_EQ() macros to be in the correct order: 
EXPECT_EQ(expected, actual) .  This will make error messages understandable as
it uses terms such as "expected" and "actual" based on the order of arguments.
