So that the two operations in DwarfDebug couldn't get separated (because
I accidentally separated them in some work in progress), put them

DwarfCompileUnit, since it's not relevant to type units.

PrevSection/PrevCU are used to detect holes in the address range of a CU
to ensure the DW_AT_ranges does not include those holes. When we see a
function with no debug info, though it may be in the same range as the
prior and subsequent functions, there should be a gap in the CU's
ranges. By setting PrevCU to null in that case, the range would not be
extended to cover the gap.

This is a first pass at a scheduling model for Jaguar.
It's structured largely on the existing SandyBridge and SLM sched models.
Using this model, in addition to turning on the PostRA scheduler, results in
some perf wins on internal and 3rd party benchmarks. There's not much difference
in LLVM's test-suite benchmarking subset of tests.

Summary:
This directive is used to reset the assembler options to their initial values.
Assembly programmers use it in conjunction with the ".set mipsX" directives.
This patch depends on the .set push/pop directive (http://reviews.llvm.org/D4821).

Summary:
This patch moves the profile reading logic out of the Sample Profile
transformation into a generic profile reader facility in
lib/ProfileData.
The intent is to use this new reader to implement a sample profile
reader/writer that can be used to convert sample profiles from external
sources into LLVM.
This first patch introduces no functional changes. It moves the profile
reading code from lib/Transforms/SampleProfile.cpp into
lib/ProfileData/SampleProfReader.cpp.
In subsequent patches I will:
- Add a bitcode format for sample profiles to allow for more efficient
encoding of the profile.
- Add a writer for both text and bitcode format profiles.
- Add a 'convert' command to llvm-profdata to be able to convert between
the two (and serve as entry point for other sample profile formats).

This solves the problem of having a kill flag inside a loop
with a definition of the register prior to the loop:
%vreg368<def> ...
Inside loop:
%vreg520<def> = COPY %vreg368
%vreg568<def,tied1> = add %vreg341<tied0>, %vreg520<kill>
=> was coalesced into =>
%vreg568<def,tied1> = add %vreg341<tied0>, %vreg368<kill>
MachineVerifier then complained:
*** Bad machine code: Virtual register killed in block, but needed live out. ***
The kill flag for %vreg368 is incorrect, and is cleared by this patch.
This is similar to the clearing done at the end of
MachineSinking::SinkInstruction().

When compiling without SSE2, isTruncStoreLegal(F64, F32) would return Legal, whereas with SSE2 it would return Expand. And since the Target doesn't seem to actually handle a truncstore for double -> float, it would just output a store of a full double in the space for a float hence overwriting other bits on the stack.

Previously, fast-isel would not clean up after failing to select a call
instruction, because it would have called flushLocalValueMap() which moves
the insertion point, making SavedInsertPt in selectInstruction() invalid.
Fixing this by making SavedInsertPt a member variable, and having
flushLocalValueMap() update it.
This removes some redundant code at -O0, and more importantly fixes PR20863.
