61bed2fe76 Do not let 'ftostr' return a string that starts with spaces. This allows 
the AsmWriter to emit FP constants like 1.0 in normal exponential notation
instead of hex notation.

e6cd7187d5 Joining the quote fray... 
Reverting the quote patch.  For some reason, this breaks the building of
llvm/runtime (the shell doesn't like it for some reason).  I might play
with it to see if I can get the quotes done in such a way that the shell
like it, but no promises.

93fc4bd9cb This hunk: 
-  unsigned TrueValue = getReg(TrueVal, BB, BB->begin());
+  unsigned TrueValue = getReg(TrueVal);

Fixes the PPC regressions from last night.

The other hunk is just a clarity improvement.

a38d8140b6 Avoid use of -fomit-frame-pointer on FreeBSD platforms. It causes thrown

of this problem.

1087b72875 Eliminate the use of the global variable hack in the X86 target that was used 
to get Visual Studio to link in X86.lib to the executables that need it.  There
is another way of doing it.

0d6f03e52b Two changes here: 
1. Add new instructions for checking parity flags: JP, JNP, SETP, SETNP.
2. Set the isCommutable and isPromotableTo3Address bits on several
   instructions.

c1feb0c8fe Make the 2-address instruction lowering pass smarter in two ways: 
1. If we are two-addressing a commutable instruction and the LHS is not the
   last use of the variable, see if the instruction is the last use of the
   RHS.  If so, commute the instruction, allowing us to avoid a
   register-register copy in many cases for common instructions like ADD, OR,
   AND, etc on X86.
2. If #1 doesn't hold, and if this is an instruction that also existing in
   3-address form, promote the instruction to a 3-address instruction to
   avoid the register-register copy.  We can do this for several common
   instructions in X86, including ADDrr, INC, DEC, etc.

This patch implements test/Regression/CodeGen/X86/commute-two-addr.ll,
overlap-add.ll, and overlap-shift.ll when I check in the X86 support for it.
