f68530e26e Remove ignore from LLVMC/TestWarnings.td. This avoids 
https://bugs.kde.org/show_bug.cgi?id=231257 and seems not to have been
needed in the first place.

4950930fa7 Finally change the instruction looking map to be a densemap from 
record* -> instrinfo instead of std::string -> instrinfo.

This speeds up tblgen on cellcpu from 7.28 -> 5.98s with a debug
build (20%).

16289314f6 Bugpoint's default memory limit (100MB) was too low for valgrind, so 
this patch raises the default to 800MB when valgrind's active.  800
was chosen semi-arbitrarily.

938747fc7f Now that tblgen can handle matching implicit defs of instructions 
to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking
two inputs (which have to be the same type) and *returning an i32*.
This is how the SDNodes get made in the graph, but we weren't able
to model it this way due to deficiencies in the pattern language.

Now we can change things like this:

 def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
-                  [(X86cmp RFP80:$lhs, RFP80:$rhs),
-                   (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i)
+                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

and fix terrible crimes like this:

-def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
+def : Pat<(X86cmp GR8:$src1, 0),
           (TEST8rr GR8:$src1, GR8:$src1)>;

This relies on matching the result of TEST8rr (which is EFLAGS, which is
an implicit def) to the result of X86cmp, an i32.

5becdf478d infer results of a pattern from implicit defs. This allows you to do something 
like this:

 def : Pat<(add ...),
           (FOOINST)>;

When fooinst only has a single implicit def (e.g. to R1).  This will be handled
as if written as (set R1, (FOOINST ...))

f8dd45b2f1 Work around a valgrind oddity where it doesn't pass the full path of a 
script to the #! command by using bash instead of /bin/sh.  Bash
searches $PATH for its script argument, but dash, which /bin/sh
resolves to on some systems, does not.
https://bugs.kde.org/show_bug.cgi?id=231257 tracks the valgrind
problem.

ab14df376a MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement a 
temporary workaround for matching inc/dec on x86_64 to the correct instruction.
 - This hack will eventually be replaced with a robust mechanism for handling
   matching instructions based on the available target features.
