compiler: Escape analysis.

By Chris Manghane.

Comprises three changes to gofrontend repository:

compiler: Add escape information to export data.

compiler: Stack-allocate non-escaping variables.

This change allows variables initialized through make or new
to be allocated on the stack via a temporary variable if they
do not escape their function. It also improves the analysis to
consider situations where variables escape in the standard
library and go testsuite such as:

*nested composite literals and composite literal arguments
*method receivers always escaping
*escape via statements in closures referring to enclosing variables
*escape via calls with multiple return results

compiler: Basic escape analysis for the go frontend.

This is an implementation of the algorithm described in
"Escape Analysis in Java" by Choi et. al.

It relies on dataflow information to discover variable
references to one another. Handles assignments to closures
and association between closures variables and the variables
of the enclosing scope.

Dataflow analysis does not discover references through range
statements e.g. for _, v := range a will not recognize that
all values of v are references to a.

Properly handle uninitialized common symbol

Uninitialized common symbol behavior in executables is target and linker
dependent.  default_binds_local_p_3 is made public and updated to take an
argument to indicate if the linker can guarantee that an uninitialized
common symbol in the executable will still be defined (through COPY
relocation) in the executable.  If common symbol is local to executable,
default_binds_local_p_3 will treat non-external variable as defined
locally.  default_binds_local_p_2 is changed to treat common symbol as
local for non-PIE binaries.

For i386, common symbol is local only for non-PIE binaries.  For x86-64,
common symbol is local only for non-PIE binaries or linker supports copy
reloc in PIE binaries.  If a target treats common symbol as local only
for non-PIE binaries, it can define TARGET_BINDS_LOCAL_P as
default_binds_local_p_2.
