Implicit def instructions, e.g. X86::IMPLICIT_DEF_GR32, are always re-materializable and they should not be spilled.

put it in a new header System/Host.h instead.
Instead of getting the endianness from configure,
calculate it directly.

llvm-svn: 44959

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

  - Added cstor that takes no arguments to create an "invalid" location.
  - Removed non-const version of getSourceManager().
  - Renamed getSourceManager() to getManager.
  - Remover operator SourceLocatio().

and readnone for functions with bodies because it
broke llvm-gcc-4.2 bootstrap.  It turns out that,
because of LLVM's array_ref hack, gcc was computing
pure/const attributes wrong (now fixed by turning
off the gcc ipa-pure-const pass).

2. Using zero-extended value of Scale and unsigned division is safe provided
   that Scale doesn't have the sign bit set.
   Previously these 2 instructions:
        %p = bitcast [100 x {i8,i8,i8}]* %x to i8*
        %q = getelementptr i8* %p, i32 -4
   were combined into:
        %q = getelementptr [100 x { i8, i8, i8 }]* %x, i32 0,
               i32 1431655764, i32 0
   what was incorrect.
