Chris Lattner 8900ef1931 add .o file writing for inline asm in llc. Here's a silly 
demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
<inline asm>:1:2: error: unrecognized instruction
	abc incl    %eax
	^
LLVM ERROR: Error parsing inline asm

Only problem seems to be that the parser finalizes OutStreamer 
at the end of the first inline asm, which isn't what we want.
For example:

$ cat asm.c
int foo(int X) {
 __asm__ ("incl    %0" : "+r" (X));
 return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
	subq	$8, %rsp
	movl	%edi, (%rsp)
	movl	%edi, %eax
	## InlineAsm Start
	incl    %eax
	## InlineAsm End
	movl	%eax, (%rsp)
	movl	%eax, 4(%rsp)
	addq	$8, %rsp
	ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax
$ 

don't stop at inc!

a co-committed clang patch.

Chris Lattner 7012916275 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

Chris Lattner 07d09ed49a Add special case bitcode support for DebugLoc. This avoids 
having the bitcode writer materialize mdnodes for all the
debug location tuples when writing out the bc file and 
stores the information in a more compact form.  For example,
the -O0 -g bc file for combine.c in 176.gcc shrinks from
739392 to 512096 bytes.

This concludes my planned short-term debug info work.

Daniel Dunbar d821f4ac60 llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always need 
exactly two passes in that case, and don't ever need to recompute any layout,
so this is a nice baseline for relaxation performance.

Jeffrey Yasskin a6eedc3c03 Free all Constants in ~LLVMConstantImpl. We avoid assertion failures 
by dropping all references from all constants that can use other
constants before trying to destroy any of them.

I also had to free bugpoint's Module in ~BugDriver().

Jeffrey Yasskin 71bd0f4eda 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.

Chris Lattner fd381328ff add support for bugpointing the integrated assembler. Something like this 
works for me: bugpoint Output/bisort.llvm.bc -run-llc-ia -safe-run-llc

This uses llc with the integrated assembler as the test compiler and llc
without it as the safe compiler.

Duncan Sands 5674c34780 Attempt to fix random build failures seen when doing highly
