.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference

Derive DIType from DIScope. This simplifies getContext() where for members the context is a type. This also eliminates need of CompileUnitMaps maintained by dwarf writer.

for alignment into the LSDA. If the TType base offset is emitted, then put the
padding there. Otherwise, put it in the call site table length. There will be no
conflict between the two sites when placing the padding in one place.

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.

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.

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.
