Eric Christopher 6647b83087 Add a new wrapper node for a DILexicalBlock that encapsulates it and a
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

Bill Wendling 579ff6c39c N.B. This is with the new EH scheme:
The blocks with invokes have branches to the dispatch block, because that more
correctly models the behavior of the CFG. The dispatch of course has edges to
the landing pads. Those landing pads could contain invokes, which then have
branches back to the dispatch. This creates a loop. The machine LICM pass looks
at this loop and thinks it can hoist elements out of it. But because the
dispatch is an alternate entry point into the program, the hoisted instructions
won't be executed.

I wasn't able to get a testcase which was small and could reproduce all of the
time. The function_try_block.cpp in llvm-test was where this showed up.

The VMOVS widening needs to look at the implicit COPY operands.  Trying

wrong approach.

Lang Hames de7ab801cc Add a natural stack alignment field to TargetData, and prevent InstCombine from
promoting allocas to preferred alignments that exceed the natural
alignment. This avoids some potentially expensive dynamic stack realignments.

The natural stack alignment is set in target data strings via the "S<size>"
option. Size is in bits and must be a multiple of 8. The natural stack alignment
defaults to "unspecified" (represented by a zero value), and the "unspecified"
value does not prevent any alignment promotions. Target maintainers that care
about avoiding promotions should explicitly add the "S<size>" option to their
target data strings.

Devang Patel e554d5995b Add dominance check for the instruction being hoisted.
For example, MachineLICM should not hoist a load that is not guaranteed to be executed.

Jakob Stoklund Olesen ba0bc4f522 Mark the standard pseudos as isPseudo = 1.
The difference between isPseudo and isCodeGenOnly is a bit murky, but
isCodeGenOnly should eventually go away.  It is used for instructions
that are clones of real instructions with slightly different properties.

The standard pseudo-instructions never mirror real instructions, so they
are definitely in the isPseudo category.

Bruno Cardoso Lopes cc6659b2ae The Mips specific function for instruction cache invalidation cannot be
compiled on mips32r1 processors because it uses synci and rdhwr instructions
which are supported only on mips32r2, so I replaced this function with the
call to function cacheflush which works for both mips32r1 and mips32r2.

Jakob Stoklund Olesen b253f490c3 Insert dummy ED table entries for pseudo-instructions.
The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.

Add a test case for xorps which has a very high opcode that exposes this
problem.

Bill Wendling 47aac51043 Revert r141365. It was causing MultiSource/Benchmarks/MiBench/consumer-lame to
hang, and possibly SPEC/CINT2006/464_h264ref.
