Nate Begeman a6c55a3195 Revert this change since it breaks a couple of the AVX tests. 
I'm unclear if the tests are actually correct or not, but reverting for now.

Nate Begeman 842455332f Remove SSE1-4 disable when AVX is enabled. While this may be useful for development, 
it completely breaks scalar fp in xmm regs when AVX is enabled.

Jakob Stoklund Olesen 72f7e1b74f Delete the StrongPHIElimination pass, leaving only a shell. 
The StrongPHIElimination pass did not work, and nobody has worked on it for two
years.

A rewrite is underway, so I am leaving this shell pass instead of deleting it
completely.

Jakob Stoklund Olesen e7ed7b6cfd Add IntervalMap::iterator::set{Start,Stop,Value} methods that allow limited 
editing of the current interval.

These methods may cause coalescing, there are corresponding set*Unchecked
methods for editing without coalescing. The non-coalescing methods are useful
for applying monotonic transforms to all keys or values in a map without
accidentally coalescing transformed and untransformed intervals.

Rafael Espindola 675fbb2ad1 Do with uleb the same trick we now do with dwarf line/address advances. This 
avoids creating leb128 fragments and speeds up the test in PR8711 to 33s.

Rafael Espindola 57ab708bdd Try to resolve symbol differences early, and if successful create a plain 
data fragment. This reduces the time to assemble the test in 8711 from 60s to
54s.

Bill Wendling f0b36a3cfd The tLDR instruction wasn't encoded properly: 
<MCInst 2251 <MCOperand Reg:70> <MCOperand Reg:66> <MCOperand Imm:0> <MCOperand Reg:0> <MCOperand Imm:14> <MCOperand Reg:0>>

Notice that the "reg" here is 0, which is an invalid register. Put a check in
the code for this to prevent crashing.

Bob Wilson 791934e122 Support using macros for Neon intrinsics implemented without builtins. 
Intrinsics implemented with Clang builtins could already be implemented as
either inline functions or macros, but intrinsics implemented directly
(without builtins) could only be inline functions.

Devang Patel 5eed2e63f8 It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.
