2df042cb32 Make EmitIntValue more efficient and more like what we do for leb128. The
difference is much smaller (about 0.3s) but significant.

660b5fc4d0 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.

0bdf0c05b9 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.

5113cdbfff 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.

76507f14ed Add a fast path to EvaluateSymbolicAdd. This avoids computing symbol addresses
which then avoids running EnsureValid.

minute.

6db8a9f3fa 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.

0613516b16 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.

38169788fa I don't think it makes any sense to assert that the target supports SSE3 here.
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing
on the apm.ll test in CodeGen/X86 because of this assertion.
