In this patch, I introduce a new altmacro string delimiter. This review is the second review in a series of four reviews. (one for each altmacro feature: LOCAL, string delimiter, string '!' escape sign and absolute expression as a string '%' ). In the alternate macro mode, you can delimit strings with matching angle brackets <..> when using it as a part of calling macro arguments. As described in the https://sourceware.org/binutils/docs-2.27/as/Altmacro.html "<string> You can delimit strings with matching angle brackets." assumptions: 1. If an argument begins with '<' and ends with '>'. The argument is considered as a string. 2. Except adding new string mark '<..>', a regular macro behavior is expected. 3. The altmacro cannot affect the regular less/greater behavior. 4. If a comma is present inside an angle brackets it considered as a character and not as a separator.

# This test checks the altmacro string delimiter '<' and '>'.

# In this test we check the '.noaltmacro' directive.

# We expect that '.altmacro' and '.noaltmacro' will act as a switch on/off directives to the alternate macro mode.

# .noaltmacro returns the format into a regular macro handling.

# The default mode is ".noaltmacro".
