Jakob Stoklund Olesen e1c0ae6fda Revert r158700 and dependent patches r158716, r158717, and r158731. 
The original r158700 caused crashes in the gcc test suite,
g++.abi/vtable3a.C among others. It also caused failures in the libc++
test suite.

Jakob Stoklund Olesen 0f855e4263 Implement PPCInstrInfo::isCoalescableExtInstr(). 
The PPC::EXTSW instruction preserves the low 32 bits of its input, just
like some of the x86 instructions. Use it to reduce register pressure
when the low 32 bits have multiple uses.

This requires a small change to PeepholeOptimizer since EXTSW takes a
64-bit input register.

This is related to PR5997.

Meador Inge cdc0057e3c Revert predefined decl tracking. 
r158085 added some logic to track predefined declarations.  The main reason we
had predefined declarations in the input was because the __builtin_va_list
declarations were injected into the preprocessor input.  As of r158592 we 
explicitly build the __builtin_va_list declarations.  Therefore the predefined
decl tracking is no longer needed.

Chandler Carruth 198422a475 Fix PR13148, an inf-loop in StringMap. 
StringMap suffered from the same bug as DenseMap: when you explicitly
construct it with a small number of buckets, you can arrange for the
tombstone-based growth path to be followed when the number of buckets
was less than '8'. In that case, even with a full map, it would compare
'0' as not less than '0', and refuse to grow the table, leading to
inf-loops trying to find an empty bucket on the next insertion. The fix
is very simple: use '<=' as the comparison. The same fix was applied to
DenseMap as well during its recent refactoring.

Thanks to Alex Bolz for the great report and test case. =]

Jan Wen Voung 7f5d79f864 Have ARM ELF use correct reloc for "b" instr. 
The condition code didn't actually matter for arm "b" instructions,
unlike "bl".  It should just use the R_ARM_JUMP24 reloc.

Hal Finkel d465810f7c Mark most PPC register classes to avoid write-after-write. 
For processors with the G5-like instruction-grouping scheme, this helps avoid
early group termination due to a write-after-write dependency within the group.
It should also help on pipelined embedded cores.

On POWER7, over the test suite, this gives an average 0.5% speedup. The largest
speedups are:

SingleSource/Benchmarks/Stanford/Quicksort - 33%
MultiSource/Applications/d/make_dparser - 21%
MultiSource/Benchmarks/FreeBench/analyzer/analyzer - 12%
MultiSource/Benchmarks/MiBench/telecomm-FFT/telecomm-fft - 12%

Largest slowdowns:

SingleSource/Benchmarks/Stanford/Bubblesort - 23%
MultiSource/Benchmarks/Prolangs-C++/city/city - 21%
MultiSource/Benchmarks/BitBench/uuencode/uuencode - 16%
MultiSource/Benchmarks/mediabench/mpeg2/mpeg2dec/mpeg2decode - 13%
