dc103b1755 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.

3e119b0bb4 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.

2f6a820abe 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.

73a62b36c6 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.

77a1457f1a 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.

a4ebf65d00 Move check of command line options after command line parsing. 
The check to not allow -analyze and -disable-output at the same time was done
before parsing the command line flags. Therefore it never triggered, and in case
both options where used opt segfaulted. Fix this by moving this check a after
command line parsing.

5a94ed2d67 XFAIL for now. If someone with access to an ARM/Linux host wants to have a look 
that would be great. They're ARM JIT failures, so without that, it's tough.

84bd43844e This test dates from the time when llvm-gcc had problems if two types were 
named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness.  This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

922894345e Add a fast path to EvaluateSymbolicAdd. This avoids computing symbol addresses 
which then avoids running EnsureValid.
This cuts the assembly time of the testcase in PR8711 from 2:50 minutes to 1
minute.

a6ebc72f34 Simplify code in Neon intrinsics. No functional changes intended. 
For most intrinsics, there is no need to allocate a temporary to hold the
result value; just return it directly.

1410cd5668 Assign arguments of Neon intrinsic macros to local temporaries. 
Since we're casting them for the calls to the builtins, we need this to
make sure their types get checked in the same way they would if the intrinsics
were implemented as inline functions.

41bdd97d48 The sections that the ELF object writer has to create are very simple and 
contain only data. Handle them specially instead of using AddSectionToTheEnd.
This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.

54b6cd6d38 Implement the first half of LiveDebugVariables. 
Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.
