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.

b56bf581a3 Don't create a (empty) output file, and don't warn about bitcode output

Similarly, avoid creating an empty output file when --disable-output is used.

Print a warning when the -o option appears with either --analyze or
--disable-output, to indicate that the option is being ignored.

3a4a832223 The Neon "vtst" instruction takes a suffix that is the element size alone -- 
adding an "i" to the suffix, indicating that the elements are integers, is
accepted but not part of the standard syntax.  This helps us pass a few more
of the Neon tests from gcc.
