Peter Collingbourne 08b4728f51 irgen: Create functions instead of global variables for builtin hash and equal algorithms.
These are in fact functions, and have function type, so it is invalid
to represent them using global variables.

Meador Inge e6c29d6d85 [llgo] Remove support for LLVM attributes
llgo supports the application of LLVM attributes to global objects
and functions.  This "feature" is undocumented and untested.  As
discusses in D27442, it should be removed.

Andrew Wilkins 78ac1f1d42 [llgo] set debuglocs for calls in synthetic functions
Synthesized functions do not have valid locations,
and so we were not setting a debug location. Recent
changes to DI require that function call instructions
within a function having DI must have a location set.
We just set the debug location to line=0, col=0.

Meador Inge 21e53508b6 [llgo] Update to use the latest IR attribute bindings
A recent commit (r286087) to the LLVM Go bindings that

llgo.  This commit updates llgo accordingly.

Meador Inge 7695d8996f [llgo] Fix `debug` to use latest `DIBuilder` bindings
Two recent commits to the LLVM Go bindings caused breaking changes
to llgo:

  1. r284707 - Moving the `AlignInBits` field from `DIBasicType` to
               `DIAutoVariable`.

  2. r284482 - The `AlignInBits` fields going from `uint64` to `uint32`.

This commit updates llgo accordingly.

Andrew Wilkins bfb1679603 [llgo] llgoi: separate evaluation from printing
Summary:
Separate the evaluation of expressions from printing
of results. This is in preparation for splitting the
core of the interpreter out for use in alternative
interpreter frontends.

At the same time, the output is made less noisy in
response to comments on the golang-nuts announcement.
We would ideally print out values using Go syntax,
but this is impractical until we have libgo based on
Go 1.5. When that happens, fmt's %#v will handle
reflect.Value better, and so we can fix/filter type
names to remove automatically generated package names.

Andrew Wilkins 0f432aa05a [llgo] Increment "Debug Info Version"
Patch by Michal Cierniak!

This patch increments the "Debug Info Version" from 2 to 3.
This is a nop if you just want to generate binaries. I verified
that with and without this patch, when I run llgo -g on a Go
source file, I get exactly the same binary. The purpose of the
patch is to make it possible to run the llvm-dis tool. Without
the patch, it is impossible to disassemble files generated with
llgo:

  $ llgo -c -g -emit-llvm src/hello.go
  $ llvm-dis hello.o
  llvm-dis: warning: ignoring debug info with an invalid version (2) in hello.o

Switch gofrontend to using go.googlesource.com, and
update to 81eb6a3f425b2158c67ee32c0cc973a72ce9d6be.

There are various changes required to update to the
go 1.5 runtime:

typemap.go is changed to accommodate the change in representation for equal/hash algorithms, and the removal of the zero value/type.
CMakeLists.txt is updated to add the build tree to the package search path, so internal packages, which are not installed, are found.
various files changes due to removal of __go_new_nopointers; the same change as in D11863, but with NoUnwindAttribute added to the added runtime functions which are called with "callOnly".
minor cleanups in ssa.go while investigating issues with unwinding/panic handling.

Andrew Wilkins f69d45efc3 [llgo] irgen: always use TargetMachine's data layout
Summary:
Another attempt at resolving the runtime assertion
in llgoi due to data layout mismatch between module
and execution engine.

The X86 data layout constant appears to be unnecessary,
and does not match what the execution engine picks.
Using the registered Target, we pick the same data
layout as the execution engine.

While I was in the vicinity, I deleted the last
remnants of PNaCl support.

Summary:
As llgoi is installed, it must be built or the install
target will fail; there is no implicit dependency.
Adding llgoi to "ALL" makes building llgo as part of an
entire LLVM distribution a bit friendlier: you can then
just do the typical "make && make install".

Summary:
    With this patch, llgo uses ssautil.Switches

    which can then be lowered to lookup tables,
    trees, etc.

    We currently only handle integer const case
    switches. We erase the comparison blocks (other
    than the initial block), and generate a switch
    instruction at the end of the block starting
    the if-else-if chain. ssautil.Switches does
    not remove duplicate const cases (e.g. same
    operands for "||"), so we do this in llgo for
    now.
