Summary:
in case we are logging to stdout, any log lines from the forked child can be misconstrued to be
inferior output. To avoid this, we disable all logging immediately after forking.
I also fix the implementatoion of DisableAllLogChannels, which was a no-op before this commit.

TestExprDoesntBlock started failing because deadlocks behave differently with
pthread_mutex and std::mutex.
This reverts part of commit r245234.

This eliminates portability issues among platforms that don't have

This patch :
- Fixes offsets of all register sets for Mips.
- Adds MSA register set and FRE=1 mode support for FP register set.
- Separates lldb register numbers and register infos of freebsd/mips64 from linux/mips64.
- Re-orders the register numbers of all kinds for mips to be consistent with freebsd order of register numbers.

Eliminated ENABLE_128_BIT_SUPPORT and union ValueData from Scalar.cpp and use llvm::APInt and llvm::APFloat for all integer and floating point types. Also used Scalar in RegisterValue.cpp

numbers in the key name "ehframe" or "eh_frame" in addition to the deprecated

for eh_frame and stabs register numberings. This is not
complete but it's a step in the right direction. It's almost
entirely mechanical.
lldb informally uses "gcc register numbering" to mean eh_frame.
Why? Probably because there's a notorious bug with gcc on i386
darwin where the register numbers in eh_frame were incorrect.
In all other cases, eh_frame register numbering is identical to
dwarf.
lldb informally uses "gdb register numbering" to mean stabs.
There are no official definitions of stabs register numbers
for different architectures, so the implementations of gdb
and gcc are the de facto reference source.
There were some incorrect uses of these register number types
in lldb already. I fixed the ones that I saw as I made
this change.
This commit changes all references to "gcc" and "gdb" register
numbers in lldb to "eh_frame" and "stabs" to make it clear
what is actually being represented.
lldb cannot parse the stabs debug format, and given that no
one is using stabs any more, it is unlikely that it ever will.
A more comprehensive cleanup would remove the stabs register
numbers altogether - it's unnecessary cruft / complication to
all of our register structures.
In ProcessGDBRemote, when we get register definitions from
the gdb-remote stub, we expect to see "gcc:" (qRegisterInfo)
or "gcc_regnum" (qXfer:features:read: packet to get xml payload).
This patch changes ProcessGDBRemote to also accept "ehframe:"
and "ehframe_regnum" from these remotes.
I did not change GDBRemoteCommunicationServerLLGS or debugserver
to send these new packets. I don't know what kind of interoperability
constraints we might be working under. At some point in the future
we should transition to using the more descriptive names.
Throughout lldb we're still using enum names like "gcc_r0" and "gdb_r0",
for eh_frame and stabs register numberings. These should be cleaned
up eventually too.
The sources link cleanly on macosx native with xcode build. I
don't think we'll see problems on other platforms but please let
me know if I broke anyone.

Neither of these libraries has been ported to Windows. Eventually
if they are ever ported we can re-enable these tests. But more
immediately what we need to do is add new data formatters for
MSVC's STL implementation. This is tracked in
http://llvm.org/pr24460.

Another step towards isolating all language/AST specific code into the files to further abstract specific implementations of parsing types for a given language.

I made an example where I had a file named "testtesttestt .o" (16 chars) that I was able to put into a .a file and we would previously truncate the object name to "testtesttestt" since we searched for any space in the name. I believe the BSD archive docs say that filenames with spaces will use the extended format, but our current libtool doesn't so I wanted to fix it by only removing trailing spaces.

This was caused by a bug in the PTVS source file editor, which has
since been fixed and awaiting a new release. For now people using
this editor need to remember to manually remove this before
committing a file.

Most were already XFAIL'ed, but the reason for the XFAIL is that
we don't have a suitable pexpect implementation on Windows. This
isn't going to change unintentionally, so there is no reason to
XFAIL them as opposed to just skip them.
llvm.org/pr22274 tracks finding a suitable pexpect module for
Windows, which should fix many of these issues. llvm.org/pr24452
tracks the larger issue of making the entire lldb-mi test suite
work on Windows, of which finding a pexpect module is just one
component.

For Linux x86 based environments the orig_eax/orig_rax
register should be set to -1 to prevent the instruction pointer
to be decremented, which was the cause for the SIGILL exception.

SUMMARY:
Last 3bits of the watchpoint address are masked by the kernel. For example, n is
at 0x120010d00 and m is 0x120010d04. When a watchpoint is set at m, then watch
exception is generated even when n is read/written. To handle this case, instruction
at PC is emulated to find the base address of the load/store instruction. This address
is then appended to the description of the stop-info packet. Client then reads this
information to check whether the user has set a watchpoint on this address.
