directly to Index, instead of requiring the input file to be first. This makes
the examples behave more like 'clang'.

For example,
  ddunbar@giles:tmp$ echo '#include <string>' | python ~/llvm/tools/clang/bindings/python/examples/cindex/cindex-includes.py -- -x c++ - | wc -l
     114
  ddunbar@giles:tmp$ echo '#include <stdio.h>' | python ~/llvm/tools/clang/bindings/python/examples/cindex/cindex-includes.py -- -x c - | wc -l

rebuilding a typename type terminating in a template-id (with
dependent template name, naturally) as a TypenameType when, because
its context could be fully resolved, we should have been building it
as a QualifiedNameType. Fixes PR6268.

Cache the phi entry to avoid doing tons of 
PHINode::getBasicBlockIndex calls in the common case.

On my insane testcase from re2c, this speeds up CGP from

When coalescing with a physreg, remember to add imp-def and imp-kill when
dealing with sub-registers.

Also fix a related bug in VirtRegRewriter where substitutePhysReg may
reallocate the operand list on an instruction and invalidate the reg_iterator.
This can happen when a register is mentioned twice on the same instruction.

created. This ensures it's updated at all time. It means targets which perform
dynamic stack alignment would know whether it is required and whether frame
pointer register cannot be made available register allocation.
This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test
case.

Functions explicitly marked inline will get an inlining threshold slightly
more aggressive than the default for -O3. This means than -O3 builds are
mostly unaffected while -Os builds will be a bit bigger and faster.

The difference depends entirely on how many 'inline's are sprinkled on the
source.

In the CINT2006 suite, only these tests are significantly affected under -Os:

               Size   Time
471.omnetpp   +1.63% -1.85%
473.astar     +4.01% -6.02%
483.xalancbmk +4.60%  0.00%

Note that 483.xalancbmk runs too quickly to give useful timing results.
