Make the debugging dump be a full line.

Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.

This is according to my understanding reading the docs, I don't know if it
really agrees fully with what VC++ allows.

"logical" location, refer to the "instantiation" location.

Slightly speed up sema of numbers like '1' by going directly to 
TargetInfo instead of through ASTContext.

Split Support/Registry.h into two files so that we have less to
recompile every time CommandLine.h is changed.

the "physical" location of tokens, refer to the "spelling" location.
This is more concrete and useful, tokens aren't really physical objects!

For example, PIC16 needs to break a long or int constant into mulitple parts and emit multiple directives. So Allow targets to overried EmitConstantValueOnly().

Clean up previous cast optimization a bit. Also make zext elimination a bit more aggressive: if it's not necessary to emit an AND (i.e. high bits are already zero), it's profitable to evaluate the operand at a different type.

adding more information to the temporary variables names so that
they don't conflict.

a new toy hazard recognizier heuristic which attempts to direct the
scheduler to avoid clumping large groups of loads or stores too densely.

SDNode-based scheduling.

loops, hoisting instructions all the way out in one step rather
than hoisting them one nest level at a time. Also, make a few
other code simplifications. This speeds up MachineLICM
by several fold.
