Capture original source for literals
Summary:
Make HsLit and OverLitVal have original source strings, for source to
source conversions using the GHC API
This is part of the ongoing AST Annotations work, as captured in
https://ghc.haskell.org/trac/ghc/wiki/GhcAstAnnotations and
https://ghc.haskell.org/trac/ghc/ticket/9628#comment:28
The motivations for the literals is as follows
```lang=haskell
x,y :: Int
x = 0003
y = 0x04
s :: String
s = "\x20"
c :: Char
c = '\x20'
d :: Double
d = 0.00
blah = x
where
charH = '\x41'#
intH = 0004#
wordH = 005##
floatH = 3.20#
doubleH = 04.16##
x = 1
```
