23a543971e [Support] Extend SLEB128 encoding support. 
Add support for padded SLEB128 values, and support for writing SLEB128
values to buffers rather than to ostreams, similar to the existing
ULEB128 support.

d7679269a9 [Support] add decodeSLEB128() 
We already have routines to encode SLEB128 as well as encode/decode ULEB128.
This last function fills out the matrix.  I'll need this for some llvm-objdump
work I am doing.

5b776b72f6 Move get[S|U]LEB128Size() to LEB128.h. 
This commit moves getSLEB128Size() and getULEB128Size() from
MCAsmInfo to LEB128.h and removes some copy-and-paste code.

Besides, this commit also adds some unit tests for the LEB128
functions.
