Fixed up gdb-remote auxv regex issues with binary data.
Fixes two causes for https://github.com/tfiala/lldb/issues/7.
1. Ensures the inferior program has started executing, by printing
a message on output first thing (per the "message:" command line arg)
and waiting for that text to arrive before doing any checks related
to auxv support.
2. Fixes up auxv-related regex patterns to be compiled with the Python
re.MULTILINE and re.DOTALL options. The multiline is needed because
the binary data can include what look like newlines when interpreted
as text, and the DOTALL is needed to have the (.*) content portion match
newlines.
Added interrupt packet helper methods to add interrupt test sequence
packets and parse the results from them.

[ValueTracking] Extend range metadata to call/invoke
Summary:
With this patch, range metadata can be added to call/invoke including
IntrinsicInst. Previously, it could only be added to load.
Rename computeKnownBitsLoad to computeKnownBitsFromRangeMetadata because
range metadata is not only used by load.
Update the language reference to reflect this change.
Test Plan:
Add several tests in range-2.ll to confirm the verifier is happy with
having range metadata on call/invoke.
Add two tests in AddOverFlow.ll to confirm annotating range metadata to
call/invoke can benefit InstCombine.

Emit DWARF3 call frame information when DWARF3+ debug info is requested
Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting
DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the
newer CIE version when we are emitting DWARF 3 or 4. This will not reduce
compatibility, as we already emit other DWARF3/4 features, and is worth doing as
the DWARF3 spec removed some ambiguities in the interpretation of call frame
information.
It also fixes a minor bug where the "return address" field of the CIE was
encoded as a ULEB128, which is only valid when the CIE version is 3. There are
no test changes for this, because (as far as I can tell) none of the platforms
that we test have a return address register with a DWARF register number >127.

[PowerPC] Remove unnecessary load of r12 in indirect call
When looking at the 64-bit SVR4 indirect call sequence, I noticed
an unnecessary load of r12. And indeed the code says:
// R12 must contain the address of an indirect callee.
But this is not correct; in the 64-bit SVR4 (ELFv1) ABI, there is
no need to load r12 at this point. It seems this code and comment
is a remnant of code originally shared with the Darwin ABI ...
This patch simply removes the unnecessary load.

[PowerPC] Simplify and improve loading into TOC register
During an indirect function call sequence on the 64-bit SVR4 ABI,
generate code must load and then restore the TOC register.
This does not use a regular LOAD instruction since the TOC
register r2 is marked as reserved. Instead, the are two
special instruction patterns:
let RST = 2, DS = 2 in
def LDinto_toc: DSForm_1a<58, 0, (outs), (ins g8rc:$reg),
"ld 2, 8($reg)", IIC_LdStLD,
[(PPCload_toc i64:$reg)]>, isPPC64;
let RST = 2, DS = 10, RA = 1 in
def LDtoc_restore : DSForm_1a<58, 0, (outs), (ins),
"ld 2, 40(1)", IIC_LdStLD,
[(PPCtoc_restore)]>, isPPC64;
Note that these not only restrict the destination of the
load to r2, but they also restrict the *source* of the
load to particular address combinations. The latter is
a problem when we want to support the ELFv2 ABI, since
there the TOC save slot is no longer at 40(1).
This patch replaces those two instructions with a single
instruction pattern that only hard-codes r2 as destination,
but supports generic addresses as source. This will allow
supporting the ELFv2 ABI, and also helps generate more
efficient code for calls to absolute addresses (allowing
simplification of the ppc64-calls.ll test case).

[PowerPC] Do not use BLA with the 64-bit SVR4 ABI
The PowerPC back-end uses BLA to implement calls to functions at
known-constant addresses, which is apparently used for certain
system routines on Darwin.
However, with the 64-bit SVR4 ABI, this is actually incorrect.
An immediate function pointer value on this platform is not
directly usable as a target address for BLA:
- in the ELFv1 ABI, the function pointer value refers to the
*function descriptor*, not the code address
- in the ELFv2 ABI, the function pointer value refers to the
global entry point, but BL(A) would only be correct when
calling the *local* entry point
This bug didn't show up since using immediate function pointer
values is not usually done in the 64-bit SVR4 ABI in the first
place. However, I ran into this issue with a certain use case
of LLVM as JIT, where immediate function pointer values were
uses to implement callbacks from JITted code to helpers in
statically compiled code.
Fixed by simply not using BLA with the 64-bit SVR4 ABI.
