1a469385bd Actually, leave the check in. This prevents us from counting dead arguments 
as IPCP opportunities.

402e338f11 Correct the name of stosd for the AT&T syntax: 
It's stosl (l for long == 32 bit).

b214a04a16 Do not let dead constant expressions hanging off of functions prevent IPCP. 
This allows to elimination of a bunch of global pool descriptor args from
programs being pool allocated (and is also generally useful!)

5be81b837b Recognize compressed LLVM bytecode files. 
This should fix the problem of not being able to link compressed LLVM
bytecode files from LLVM libraries.

d9387fee02 Tune compression: 
bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed
       or compression ratio on all but the largest bytecode files (>1MB)
zip:   level 9 -> 6, this speeds up compression time by ~30% but only
       degrades the compressed size by a few bytes per megabyte. Those few
       bytes aren't worth the effort.

bc8bc24d28 Thanks to sabre for pointing out that we were incorrectly codegen'ing 
int test(int x) { return 32768 - x; }

Fixed by teaching the function that checks a constant's validity to be used
as an immediate argument about subtract-from instructions.

f2976f16ce Fix this function to not say that longs have 8-byte alignment on X86/PPC. 
This method is really a gross hack, but at least we can make it work on
the targets we support right now.

This bug fix stops a crash in a testcase reduced from 176.gcc

3083f2a424 Do not compute the predecessor list for a block unless we need it. 
This speeds up simplifycfg on this program, from 44.87s to 0.29s (with
a profiled build):

 #define CL0(a) case a: goto c;
 #define CL1(a) CL0(a##0) CL0(a##1) CL0(a##2) CL0(a##3) CL0(a##4) CL0(a##5) \
 CL0(a##6) CL0(a##7) CL0(a##8) CL0(a##9)
 #define CL2(a) CL1(a##0) CL1(a##1) CL1(a##2) CL1(a##3) CL1(a##4) CL1(a##5) \
 CL1(a##6) CL1(a##7) CL1(a##8) CL1(a##9)
 #define CL3(a) CL2(a##0) CL2(a##1) CL2(a##2) CL2(a##3) CL2(a##4) CL2(a##5) \
 CL2(a##6) CL2(a##7) CL2(a##8) CL2(a##9)
 #define CL4(a) CL3(a##0) CL3(a##1) CL3(a##2) CL3(a##3) CL3(a##4) CL3(a##5) \
 CL3(a##6) CL3(a##7) CL3(a##8) CL3(a##9)

 void f();

 void a() {
     int b;
  c: switch (b) {
         CL4(1)
     }
 }

This testcase is contrived to expose N^2 behavior, but this patch should speedup
simplifycfg on any programs that use large switch statements.  This testcase
comes from GCC PR17895.
