(1) An int CC live range must be spilled if there are any interferences,
    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same
register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
    phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
    deal with this.

Corrected capitalization of subheadings.
Created a new subsection for compiling the C front end and moved all references
to it there.
Updated the disk space requirements to reflect the need for the binary C front
end and the optional C front end source.
Added information on unpacking the distribution to the summary section.
Moved autoconf environment variables to the autoconf section.
Changed make to gmake.
Removed some of the precise directions for unpacking the archives.
Fixed some formatting inconsistencies (headings that were not centered).

Unfortunately, reallocation also means that the pointer numbering will
change, so increase table size to try to avoid it.

We need the native libraries for libinstr because they are directly
linked into the native CBE or LLC code.  That is the only practical
way to debug them!

some comments.

llvm-svn: 7119

* Made error messages print out what directory failed chdir()
* Put quotes around search arguments to grep
* Use `egrep' instead of `grep -e' because they are equivalent but `grep' does
  not have the `-e' option on Sparc/Solaris
* Added `--enable-jit' to the ./configure command because both X86 and Sparc
  have JITs and we want them to be tested
* Fixed the regular expressions parsing the changes in CVS which were causing
  the script to die

correct: empirically, "regType" is wrong for a number of registers. Thus, one
can only rely on the "regClass" to figure out what kind of register one is
dealing with.

This change switches to using only "regClass" and adds a few extra DEBUG() print
statements and a few clean-ups in comments and code, mostly minor.
