e701a907f2 tests: Propogate the HOME environment variable through to tests. I'm ambivalent 
about this, but it can be useful for users who use ccache, since the LLVMC tests
are fond of calling gcc.

e4b5559cf8 change the scope node to include a list of children to be checked 
instead of to have a chained series of scope nodes.  This makes
the generated table smaller, improves the efficiency of the
interpreter, and make the factoring optimization much more 
reasonable to implement.

11cce486ac This is a patch to the assembler frontend to detect when aligning a text 
section with TextAlignFillValue and calls EmitCodeAlignment() instead of
calling EmitValueToAlignment().  This allows x86 assembly code to be aligned
with optimal nops.

084112437d Revert r97064. Duncan pointed out that bitcasts are defined in 
terms of store and load, which means bitcasting between scalar
integer and vector has endian-specific results, which undermines
this whole approach.

3fb5927aea Make the side-numbering of instructions used by metadata (which is needed to 
keep track of instructions that return void) per-function. This fixes PR5278.

This breaks backwards compatibility with the metadata format. That's okay
because we haven't released the metadata bitcode yet.

ea2fcbcd28 Implement the first half of redundancy factoring: efficiently 
splitting all the patterns under scope nodes into equality sets
based on their first node.  The second step is to rewrite the
graph info a form that exposes the sharing.  Before I do this, 
I want to redesign the Scope node.

52ed61204b Make LoopSimplify change conditional branches in loop exiting blocks 
which branch on undef to branch on a boolean constant for the edge
exiting the loop. This helps ScalarEvolution compute trip counts for
loops.

Teach ScalarEvolution to recognize single-value PHIs, when safe, and
ForgetSymbolicName to forget such single-value PHI nodes as apprpriate
in ForgetSymbolicName.

c443274bc1 Dump the presence of attached metadata even if we don't know what it is. This 
format is not parsable, even if the module is legal. To get parsable output,
dump the module instead of the function or smaller, since metadata kind are
attached to the module (not the context).

e76255b080 Large stack frame patch for the CellSPU: handle stack frames that exceed 8176 
(511*16) bytes register displacement (D-form).

NOTE: This is a potential headache, given the SPU's local core limitations,
allowing the software developer to commit stack overrun suicide unknowingly.
Also, large SPU stack frames will cause code size explosion. But, one presumes
that the software developer knows what they're doing...

e22e8b7621 LLVM puts padding bytes in the __gcc_except_tab section after the 
GCC_except_table label but before the Lexception, which the FDE references.
This causes problems as the FDE does not point to the start of an LSDA chunk.

Use an unnormalized uleb128 for the call-site table length that includes the
padding.
