Change the check for constant-conversion with width-1 bitfields so it doesn't suppress quite as many cases. Based off a testcase in the gcc testsuite.

Turn off implicit truncation warning for compound assignment to bitfields; it might be reasonable in some cases, but it clearly doesn't make sense in some cases, like the included testcase.

Make the bitfield implicit truncation warning slightly more aggressive, and make the printed warning a bit more accurate. The new behavior matches gcc's -Wconversion. <rdar://problem/10238797>.

Only emit implicit constant conversion truncation warnings in reachable code. Apparently this is what GCC does, and some code depends on this. Fixes <rdar://problem/10321089>.

Undo a refactor-o and base the bitfield-truncation warning on the
uncoerced value. Also, whitelist bool bitfields, which aren't
really a truncation.

When -Wconversion computes the range of a type, it uses the (bit-)range
of the enumerators rather than the actual expressible range. This is
great when dealing with opaque *values* of that type, but when computing
the range of the type for purposes of converting *into* it, it produces
warnings in cases we don't care about (e.g. enum_t x = 500;). Divide
the logic into these two cases and use the more conservative range for
targets.

Tweak to bitfield-overflow warning: don't warn about storing
a positive value into a signed bitfield of the exact width of
the value.

Split out -Wconversion warnings about constant precision into their
own subcategory, -Wconstant-conversion, which is on by default.
Tweak the constant folder to give better results in the invalid
case of a negative shift amount.
