of a std::string.  This avoids copying the string to the heap in common
cases.  Patch by Pratik Solanki!

instead of passing the name into the instruction ctors.  Since most 
instruction ctors take their name as an std::string, this avoids copying the
string to the heap and a malloc and free.

Add two new file to codegen project (VS).
This unbreak the build for VS.

Add new file to Sema Project for VS.
this unbreak the build for VS2005 (with the associated patch on llvm).

warning when creating the archive (the warning
causes the test to fail).

This speeds up a particular testcase from 0.0302s to 0.0222s in LiveVariables.

llvm-svn: 52819

This speeds up LiveVariables from 0.6279s to 0.6165s on kimwitu++.

tolerate a non-nul-terminated string, and handling a direct global 
reference.

llvm-svn: 52813

global is constant already.  No functionality change.

Don't perform expensive queries checking for super and sub registers when we know that there aren't any.
This speed up LiveVariables on instcombine at -O0 -g from 0.3855s to 0.3503s.  Look for more improvements in this area soon!

- Make sure that we're not recalculating the size of a vector
  that never changes.

llvm-svn: 52803

some uses of std::vector, where it's return std::vector by value. Yuck!

Additionally, define __clang__ so clients can predicate based on
clang features.

improves AsmPrinter runtime on instcombine from 0.3920s to 0.3836s.
