1b346b7f8f Enable code to emit dbg.declare as DEBUG_VALUE
comments (fast isel, X86).  This doesn't seem
to break any functionality, but will introduce
cases where -g affects the generated code.  I'll
be fixing that.

cd5adbbc0c my instcombine transformations to make extension elimination more
aggressive changed the canonical form from sext(trunc(x)) to ashr(lshr(x)),
make sure to transform a couple more things into that canonical form,
and catch a case where we missed turning zext/shl/ashr into a single sext.

1ad0e8b576 Canonicalize -1 - x to ~x.
Instcombine does this but apparently there are situations where this pattern will escape the optimizer and / or created by isel. Here is a case that's seen in JavaScriptCore:
  %t1 = sub i32 0, %a
  %t2 = add i32 %t1, -1
The dag combiner pattern: ((c1-A)+c2) -> (c1+c2)-A
will fold it to -1 - %a.

eb231ce51d The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in
the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
indirect branch).  Instead of '1', it should be specified as '?', because GPR
only specifies the register class, which includes both hi-and-lo registers.

acd03ae679 Get MCSymbol out of the mangling business, and move all the logic
to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.
