ARM FastISel fix sext/zext fold
Sign- and zero-extension folding was slightly incorrect because it wasn't checking that the shift on extensions was zero. Further, I recently added AND rd, rn, #255 as a form of 8-bit zero extension, and failed to add the folding code for it.
This patch fixes both issues.

Make host ARM CPU feature detection independent of the vendor
For ARM on linux we use /proc/cpuinfo to detect the host CPU's features.
Linux derives these values without ever looking at the vendor of the
specific CPU implementation. Hence, it adds little value, if we parse
the output of /proc/cpuinfo only for certain vendors.
This patch enables us to derive the correct feature flags e.g. for Qualcomm
CPUs.

[PECOFF] Remove COFF header from PE header for simplicity.
COFF header is always present both in executable and in object file. PE header
is present only in executable. So the natural way to handle PE/COFF file is
treating COFF is mandatory header and PE is optional. Current data structre
does not allow it, because PE header includes COFF header. Removing COFF

Fix ARM unwind opcode assembler in several cases.
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 MemCpyOpt pass is capable of optimizing:

Assertion is triggered when the compiler tries to evalute "sizeof(typeof(D))",
while D is an opaque-typed, 'sret' formal argument of function being compiled.
i.e. the signature of the func being compiled is something like this:
T caller(...,%opaque* noalias nocapture sret %D, ...)
