Log message:
Compile clang with clang by default instead of egcc.  This allows our
build system to selfhost itself after the initial clang bootstrap
without relying on an external compiler.  Setting BOOTSTRAP_CLANG
allows bootstrapping clang with egcc.

Fix operand of pushq instruction; clang's integrated assembler is less
forgiving than gas and insists that we use a 64-bit integer.  No binary

Modified files:
sys/arch/amd64/amd64: acpi_wakecode.S mptramp.S 

Log message:
Generating mixed 16-bit/32-bit/64-bit code with clang's integrated
assembler is a bit tricky.  It supports the .code16, .code32 and
.code64 directives.  But it doesn't know about the data16/data32 and
addr16/addr32 instruction prefixes.  Instead it tries to determine
those from the instruction opcode.  It mostly succeeds, but there are
a couple of corner cases where clang will generate the "addr32" form
where gas generates the "addr16" form in .code16 segments.  That
should be no problem (and just waste a couple of bytes), but it makes
comparing the generated code a bit difficult.

Allow the trampoline code to be compiled with both.  For clang #define
away the addr32 prefix and avoid using the data32 prefix by using a
mnemonic that explicitly encodes the size of the operand.  Add a few
addr32 prefixes in .code16 blocks to reduce the differences between
code generated by clang and gas.
