36b8e53fe0 Include the source type in SCEV cast expression debug output, and 
print sext, zext, and trunc, instead of signextend, zeroextend,
and truncate, respectively, for consistency with the main IR.

578ccf81e5 When turning (ashr(shl(x, n), n)) into sext(trunc(x)), the width of the 
type to truncate to should be the number of bits of the value that are
preserved, not the number that are clobbered with sign-extension.
This fixes regressions in ldecod.
