In the runtime there are specialized fast map routines for
certain kep types. This CL lets the compiler make use of these
functions, instead of always using the generic ones.
As we now generate multiple versions of map delete calls, to make
things easier we delay the expansion of the built-in delete
function to flatten phase.

* config/ia64/crtbegin.S (__dso_handle): Put in .sdata/.sbss
rather than .data/.bss so it can be accessed via gp-relative
addressing.

Scan inlinable methods for references to global variables and
functions (forgot to do that earlier).
Track all packages mentioned by exports (that should have been done
earlier too).
Record assembler name in export data, so that we can inline calls to
non-Go functions. Modify gccgoimporter code to skip assembler name.
This increases the number of inlinable functions in the standard
library from 215 to 439.

When converting a constant to interface, such as interface{}(42)
or interface{}("hello"), if the interface escapes, we currently
generate a heap allocation to hold the constant value.
This CL changes it to generate a static allocation instead, as
the gc compiler does. This reduces allocations in such cases.

This fixes some testcases that the last fifteen or so patches broke.
In all these cases we no longer need to set VSX_REG_ATTR: the default
value of "wa" is correct.

wp becomes wa with isa p9tf, and wq is replaced by wa with isa p9kf.

We don't need the <VSs> mode attribute, if we make <sd> work for V4SF

This removes the <Ftrad>, <Fvsx>, and <Fs> mode attributes, and creates
new <sd> and <s> mode attributes instead. <sd> is either "s" or "d",
depending on whether the mode is single-precision or double-precision
floating point; and <s> is either "s" or nothing.

When used in VSX_B, VSX_D, or VSX_F, both <VSr> and <VSa> are always
just "wa" now. Similarly <VSr2> and <VSr3>. The former of those is
always "wa", so we can remove the mode attribute completely.
* config/rs6000/vsx.md (define_mode_attr VSr2): Delete.
(rest of file): Replace all <VSa>, <VSr>, <VSr2>, and <VSr3> that are
used with VSX_B, VSX_D, or VSX_F, with just "wa".
