[Tobias von Koch] What's happening here is that the CR6SET/CR6UNSET is breaking the chain of register copies glued to the function call (BL_SVR4 node). The scheduler then moves other instructions in between those and the function call, which isn't good!

Right. That's the case where there is no chain of register copies before the call, so InFlag == 0... Attached is a new revision of the patch which should fix this for good.

The old PHI updating code in loop-rotate was replaced with SSAUpdater a while
ago, it has no problems with comples PHIs. What had to be fixed is detecting
whether a loop was already rotated and updating dominators when multiple exits
were present.

This change increases overall code size a bit, mostly due to additional loop
unrolling opportunities. Passes test-suite and selfhost with -verify-dom-info.
Fixes PR7447.

Thanks to Andy for the input on the domtree updating code.

When a MachineInstr is constructed, its implicit operands are added
first, then the explicit operands are inserted before the implicits.

MCInstrDesc has oprand flags like early clobber and operand ties that
apply to the explicit operands.

Don't look at those flags when the implicit operands are first added in
the explicit operands's positions.

expansion, but the new definition is used for any subsequent occurences within
the argument list or after the expansion.

take the parameters from the declarator directly.

This includes:
  - The isl_id of the domain of the scattering must be copied from the original
    domain
  - Remove outdated references to a 'FinalRead' statement
  - Print of the Pocc output, if -debug is provided.
  - Add line breaks to some error messages.

This improves compatibility with gcc in this regard, and this file generation
can be ameliorated with GCOV_PREFIX and GCOV_PREFIX_STRIP. It's also useful if
your build directory doesn't specify -o <abspath> and it uses a recursive make
structure, so it's not relative to the toplevel.

Changes the hash result for strings containing characters
with values >= 128, such as UTF8 strings (not normal ASCII).

Changed mostly so we match other implementations.

- The root cause is that target constant materialization in X86 fast-isel
  creates a PC-rel addressing which may overflow 32-bit range in non-Small code
  model if .rodata section is allocated too far away from code segment in
  MCJIT, which uses Large code model so far.
- Follow the similar logic to fix non-Small code model in fast-isel by skipping
  non-Small code model.
