516867fd79 Move dbg_value generation to target-independent FastISel, 
as X86 is currently the only FastISel target.  Per review.

ae14b0d790 switch from my nice hashtable based merging solution to a 
gross little neighbor merging implementation.  This one has
the benefit of not violating the ordering of patterns, so it
generates code that passes tests again.

938c57ccc6 finish off the factoring optimization along the lines of the 
current design.  This generates a matcher that successfully
runs, but it turns out that the factoring we're doing violates
the ordering of patterns, so we end up matching (e.g.) movups
where we want movaps.  This won't due, but I'll address this in
a follow on patch.  It's nice to not be on by default yet! :)

6f18300453 add a new setNumChildren method for resizing scopes. Tweak getHash() so 
that we never return a tombstone value, which (thankfully) triggers an
assert in densemap.

56ab10dfb2 Currently in LLVM, names of libcalls are assigned during TargetLowering 
object construction. There is no provision to change them when the 
code for a function generated. 
So we have to change these names while printing assembly.

01f5df01bf fix the matcher in the presence of multiple scopes: we need to save 
and restore the entire matcher stack by value.  This is because children
we're testing could do moveparent or other things besides just 
scribbling on additions to the stack.

173d797171 Add another (and hopefully the last) exception case, where once we recalculate 
the alignment requirement, if it no longer makes the TType base offset overflow
into extra bytes, then we need to pad to those bytes ourselves.

788d3707a8 Catch a corner case where adding the padding to the "TType base offset" field 
will eliminate the need for padding in the "Call site table length". E.g., if
we have this:

    GCC_except_table1:
    Lexception1:
        .byte   0xff  ## @LPStart Encoding = omit
        .byte   0x9b  ## @TType Encoding = indirect pcrel sdata4
        .byte   0x7f  ## @TType base offset
        .byte   0x03  ## Call site Encoding = udata4
        .byte   0x89  ## Call site table length

with padding of 1. We want to emit the padding like this:
 
    GCC_except_table1:
    Lexception1:
        .byte   0xff  ## @LPStart Encoding = omit
        .byte   0x9b  ## @TType Encoding = indirect pcrel sdata4
        .byte   0xff  ## @TType base offset
        .space  1,0   ## Padding
        .byte   0x03  ## Call site Encoding = udata4
        .byte   0x89  ## Call site table length

and not with padding on the "Call site table length" entry.

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.
