MachineDebugInfo tables.

3fdde110eb Checking the wrong value. This caused us to emit silly code like 
Y = seteq bool X, true
instead of just using X :)

45090476be Sparc actually *DOES* have a directive for emitting zeros. In fact, it requires 
it, because this:

.bss
X:
.byte 0

results in the assembler warning: "initialization in bss segment".  Annoying.

6fa1f57c66 Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc. 
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

197ab8787f HP aCC (and a bunch of other compilers, no doubt) don't share 
GCC's syntax for auto-dependency generation stuff. This should
be changed to be disabling dependency stuff unless GCC/ICC is
found.

80a8a26d07 previously, configure would die if GCC or ICC was not found. Now it'll 
go through, but we do want to know if we're using GCC/ICC since they
share certain funky command line options (for dependency generation
stuff)

0ab9f966de Canonicalize inner loops before outer loops. Inner loop canonicalization

0d7db6f79a If we have zero initialized data with external linkage, use .zerofill to 
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.
