Jason Molenda b4a8b4c401 Performance improvement: Change lldb so that it puts a breakpoint
on the first branch instruction after a function return (or the end
of a source line), instead of a breakpoint on the return address,
to skip an extra stop & start of the inferior process.

I changed Process::AdvanceAddressToNextBranchInstruction to not
take an optional InstructionList argument - no callers are providing
a cached InstructionList today, and if this function was going to
do that, the right thing to do would be to fill out / use a
DisassemblerSP which is a disassembler with the InstructionList for
this address range.

Siva Chandra 9293fc4185 Better scheme to lookup alternate mangled name when looking up function address.
Summary:
This change is relevant for inferiors compiled with GCC. GCC does not
emit complete debug info for std::basic_string<...>, and consequently, Clang
(the LLDB compiler) does not generate correct mangled names for certain
functions.

This change removes the hard-coded alternate names in
ItaniumABILanguageRuntime.cpp.

Before the hard-coded names were put in ItaniumABILanguageRuntime.cpp, one could
not evaluate std::string methods (ex. std::string::length). After putting in
the hard-coded names, one could evaluate them. However, it did not still
enable one to call methods on, say for example, std::vector<string>.
This change makes that possible.

There is some amount of incompleteness in this change. Consider the
following example:

std::string hello("hello"), world("world");
std::map<std::string, std::string> m;
m[hello] = world;

One can still not evaluate the expression "m[hello]" in LLDB. Will
address this issue in another pass.

Ewan Crawford 26e52a7074 [RenderScript] Improve file format for saving RS allocations
Updates the file format for storing RS allocations to a file, so that the format now supports struct element types.

The file header will now contain a subheader for every RS element and it's descendants. 
Where an element subheader contains element type details and offsets to the subheaders of that elements fields. 

Patch also improves robustness when loading incorrect files.

Dawn Perchik 954b40bf63 Add support for "source info" and use it to fix MI's -symbol-list-lines.
This patch adds support the command 'source info' as follows:
    (lldb) help source info
         Display source line information (as specified) based on the current executable's
         debug info.
    
    Syntax: source info <cmd-options>
    
    Command Options Usage:
      source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
      source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
      source info [-c <count>] [-a <address-expression>]
    
           -a <address-expression> ( --address <address-expression> )
                Lookup the address and display the source information for the corresponding
                file and line.
    
           -c <count> ( --count <count> )
                The number of line entries to display.
    
           -e <linenum> ( --end-line <linenum> )
                The line number at which to stop displaying lines.
    
           -f <filename> ( --file <filename> )
                The file from which to display source.
    
           -l <linenum> ( --line <linenum> )
                The line number at which to start the displaying lines.
    
           -n <symbol> ( --name <symbol> )
                The name of a function whose source to display.
    
           -s <shlib-name> ( --shlib <shlib-name> )
                Look up the source in the given module or shared library (can be specified
                more than once).
For example:
    (lldb) source info --file x.h
    Lines for file x.h in compilation unit x.cpp in `x
    [0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
    [0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10

The new options are used to fix the MI command:
    -symbol-list-lines <file>
which didn't work for header files because it called:
    target modules dump line-table <file>
which only dumps line tables for a compilation unit.

The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
    (lldb) target modules dump line-table
    error:
    Syntax:
    error: no source filenames matched any command arguments
Now you get:
    error: file option must be specified.

Pointer keys in a DenseMap have their low bits used by the map

alignment of the pointer. We can only do this if we have the complete
type of the pointee. This is part of larger cleanup across LLVM and
