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

recompile every time CommandLine.h is changed.

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.

than hoisting them one nest level at a time. Also, make a few
other code simplifications. This speeds up MachineLICM
by several fold.

and into the ScheduleDAGInstrs class, so that they don't get
destructed and re-constructed for each block. This fixes a
compile-time hot spot in the post-pass scheduler.

To help facilitate this, tidy and do some minor reorganization
in the scheduler constructor functions.

 A = 1U,

Don't make an implicit cast expr of null for B.
