the Mips16 port. A few of the psuedos could either take signed
or unsigned arguments and I did not distinguish the case and improperly
rejected some valid cases that the assembler had previously accepted
when they were pure pseudos that expanded as assembly instructions.

No functionality change. CGCleanup.cpp provides the implementation for
EHScopeStack, so it seems more consistent to place the class definition
in CGCleanup.h.
This should also help solve a header ordering problem that I have.

Since we have ARM unwind directive parser and assembler, we
can check the correctness in two stages:
1. From LLVM assembly (.ll) to ARM assembly (.s)
2. From ARM assembly (.s) to ELF object file (.o)
We already have several "*.s to *.o" test cases. This CL adds
some "*.ll to *.s" test cases and removes the redundant "*.ll to *.o"
test cases.
New test cases to check "*.ll to *.s" code generator:
- ehabi.ll: Check the correctness of the generated unwind directives.
- section-name.ll: Check the section name of functions.
Removed test cases:
- ehabi-mc-cantunwind.ll
(Covered by ehabi-cantunwind.ll, and eh-directive-cantunwind.s)
- ehabi-mc-compact-pr0.ll
(Covered by ehabi.ll, eh-compact-pr0.s, eh-directive-save.s, and
eh-directive-setfp.s)
- ehabi-mc-compact-pr1.ll
(Covered by ehabi.ll, eh-compact-pr1.s, eh-directive-save.s, and
eh-directive-setfp.s)
- ehabi-mc.ll
(Covered by ehabi.ll, and eh-directive-integrated-test.s)
- ehabi-mc-section-group.ll
(Covered by section-name.ll, and eh-directive-section-comdat.s)
- ehabi-mc-section.ll
(Covered by section-name.ll, and eh-directive-section.s)
- ehabi-mc-sh_link.ll
(Covered by eh-directive-text-section.s, and eh-directive-section.s)

Changes to ARM unwind opcode assembler:
* Fix multiple .save or .vsave directives. Besides, the
order is preserved now.
* For the directives which will generate multiple opcodes,
such as ".save {r0-r11}", the order of the unwind opcode
is fixed now, i.e. the registers with less encoding value
are popped first.
* Fix the $sp offset calculation. Now, we can use the
.setfp, .pad, .save, and .vsave directives at any order.
Changes to test cases:
* Add test cases to check the order of multiple opcodes
for the .save directive.
* Fix the incorrect $sp offset in the test case. The
stack pointer offset specified in the test case was
incorrect. (Changed test cases: ehabi-mc-section.ll and
ehabi-mc.ll)
* The opcode to restore $sp are slightly reordered. The
behavior are not changed, and the new output is same
as the output of GNU as. (Changed test cases:
eh-directive-pad.s and eh-directive-setfp.s)

The register classes when emitting loads weren't quite restricting enough, leading to MI verification failure on the result register.
These are new failures that weren't there the first time I tried enabling ARM FastISel for new targets.

This is a slight tweak of r180708; It avoids incrementing depth when non-template local classes nested within member templates of local classes are encountered.
This patch was LGTM'd by Doug http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130506/079656.html and passed the regression tests that normally pass (i.e. excluding many Module and Index tests on Windows that fail regardless)

I ran clang-format on my patch but it seemed to have wreaked havoc with new lines - might have to do with using it on windows :( will resubmit once i've cleaned this issue up. sorry.

r183614 was failing because va_list on some platforms is defined in a
similar manner. This test fails on Windows with r183614 applied.

This helps preserve the type-as-written in the AST, which we need for
MSVC mangling. In particular, we need to preserve the types of array
parameters in function pointer types.
The essence of this change is:
- QualType ArgTy = Param->getType();
+ QualType ArgTy = Param->getTypeSourceInfo()->getType();
... followed by the adjustment in ActOnFunctionDeclarator().

Handle the case when the disassembler table can't tell
the difference between some encodings of QADD and CPS.
Add some necessary safe guards in CPS decoding as well.

Several LLVM headers are moved. The code listings in
LLVM tutorial are not updated yet.
This CL removes the code replica in the .rst, and replace
them with a literalinclude directive, so that sphinx can
include the latest code automatically.

r183584 tries to derive some info from the code *AFTER* a call and apply
these derived info to the code *BEFORE* the call, which is not always safe
as the call in question may never return, and in this case, the derived
info is invalid.
Thank Duncan for pointing out this potential bug.

sys::IdentifyFileType is already conscious of the length, and
object_error::invalid_file_type is returned below anyway if
sys::IdentifyFileType doesn't recognize the file.
