Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.
If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.
Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.
Finally, the test suite runs 33% faster on Linux now. ;]

Make tests which first provide a negative assertion via 'not', then
a pipeline, and then a positive assertion via grep, use two RUN lines
instead.
Supporting these complex ideas of 'success' and 'failure' across
multiple stages of a pipeline is brittle in the shell world, and would
block switching to ShTest format; it only worked due to contrivances
introduced by the TclTest format.
Writing this as two separate RUN lines seems clearer in any event.

Switch a bunch of Linker tests from using elaborate echo productions to
just provide and reference separate input files from an Inputs
subdirectory. This pattern works very well in the Clang tree and is
easier to understand in my opinion. It also has fewer limitations and
will remove one particularly annoying use of TCL-style {} quoting from

subdirectories used due to fortuitous suffix patterns.

Precompute SCEV pointer analysis prior to instruction fusion in BBVectorize.
When both a load/store and its address computation are being vectorized, it can
happen that the address-computation vectorization destroys SCEV's ability
to analyize the relative pointer offsets. As a result (like with the aliasing
analysis info), we need to precompute the necessary information prior to
instruction fusing.
This was found during stress testing (running through the test suite with a very
low required chain length); unfortunately, I don't have a small test case.

Allow BBVectorize to form non-2^n-length vectors.
The original algorithm only used recursive pair fusion of equal-length
types. This is now extended to allow pairing of any types that share
the same underlying scalar type. Because we would still generally
prefer the 2^n-length types, those are formed first. Then a second
set of iterations form the non-2^n-length types.
Also, a call to SimplifyInstructionsInBlock has been added after each
pairing iteration. This takes care of DCE (and a few other things)
that make the following iterations execute somewhat faster. For the
same reason, some of the simple shuffle-combination cases are now
handled internally.
There is some additional refactoring work to be done, but I've had
many requests for this feature, so additional refactoring will come

The ELF relocation record format is different for N64
which many Mips 64 ABIs use than for O64 which many
if not all other target ABIs use.
Most architectures have the following 64 bit relocation record format:
typedef struct
{
Elf64_Addr r_offset; /* Address of reference */
Elf64_Xword r_info; /* Symbol index and type of relocation */
} Elf64_Rel;
typedef struct
{
Elf64_Addr r_offset;
Elf64_Xword r_info;
Elf64_Sxword r_addend;
} Elf64_Rela;
Whereas N64 has the following format:
typedef struct
{
Elf64_Addr r_offset;/* Address of reference */
Elf64_Word r_sym; /* Symbol index */
Elf64_Byte r_ssym; /* Special symbol */
Elf64_Byte r_type3; /* Relocation type */
Elf64_Byte r_type2; /* Relocation type */
Elf64_Byte r_type; /* Relocation type */
} Elf64_Rel;
typedef struct
{
Elf64_Addr r_offset;/* Address of reference */
Elf64_Word r_sym; /* Symbol index */
Elf64_Byte r_ssym; /* Special symbol */
Elf64_Byte r_type3; /* Relocation type */
Elf64_Byte r_type2; /* Relocation type */
Elf64_Byte r_type; /* Relocation type */
Elf64_Sxword r_addend;
} Elf64_Rela;
The structure is the same size, but the r_info data element
is now 5 separate elements. Besides the content aspects,
endian byte reordering will be different for the area with
each element being endianized separately.
I treat this as generic and continue to pass r_type as
an integer masking and unmasking the byte sized N64
values for N64 mode. I've implemented this and it causes no
affect on other current targets.
This passes make check.
